NAME
blackhole6 - A tool to find IPv6 blackholes
SYNOPSIS
blackhole6 DESTINATION [PARAMETERS]
DESCRIPTION
blackhole6 is a tool to isolate IPv6 blackholes.
SCRIPTS
get-mx
This script takes no further arguments, and operates as follows:
+ The tool reads domain names from standard-input (oner per line),
and obtains the MX for the corresponding domain.
+ Lines where the first non-blank character is the numeral sign (#)
are consdered to contain comments, and hence are ignored.
+ The format of the resulting output is:
# DOMAIN_NAME (CANONIC_NAME)
MX_RECORD_1
MX_RECORD_2
get-ns
This script takes no further arguments, and operates as follows:
+ The tool reads domain names from standard-input (oner per line),
and obtains the NS records for the corresponding domain.
+ Lines where the first non-blank character is the numeral sign (#)
are consdered to contain comments, and hence are ignored.
+ The format of the resulting output is:
# DOMAIN_NAME (CANONIC_NAME)
MX_RECORD_1
MX_RECORD_2
trace-do8-tcp trace-do8-icmp trace-do256-tcp trace-do256-icmp
These scripts are meant to obtain information about where in the net-
work packets employing IPv6 Extension Headers are being dropped. They
test the path with IPv6 packets containing TCP or ICMPv6 payloads and a
Destination Options Header of 8 or 256 bytes. Based on the obtained re-
sults, the tool can infer what is the system causing the packet drops.
trace-hbh8-tcp trace-hbh8-icmp trace-hbh256-tcp trace-hbh256-icmp
These scripts are meant to obtain information about where in the net-
work packets employing IPv6 Extension Headers are being dropped. They
test the path with IPv6 packets containing TCP or ICMPv6 payloads and a
Hop-by-Hop Options Header of 8 or 256 bytes. Based on the obtained re-
sults, the tool can infer what is the system causing the packet drops.
trace-fh256-tcp trace-fh256-icmp
These scripts are meant to obtain information about where in the net-
work packets employing IPv6 Extension Headers are being dropped. They
test the path with IPv6 packets containing TCP or ICMPv6 payloads re-
sulting in IPv6 fragments of around 256 bytes. Based on the obtained
results, the tool can infer what is the system causing the packet
drops.
trace-do8-tcp-stdin trace-do8-icmp-stdin trace-do256-tcp-stdin trace-
do256-icmp-stdin
These scripts are meant to obtain information about where in the net-
work packets employing IPv6 Extension Headers are being dropped. They
test the path with IPv6 packets containing TCP or ICMPv6 payloads and a
Destination Options Header of 8 or 256 bytes. Based on the obtained re-
sults, the tool can infer what is the system causing the packet drops.
These tools read one IPv6 address per line form standard input and, for
each of those addresses, information is printed with the following syn-
tax:
trace-hbh8-tcp-stdin trace-hbh8-icmp-stdin trace-hbh256-tcp-stdin
trace-hbh256-icmp-stdin
These scripts are meant to obtain information about where in the net-
work packets employing IPv6 Extension Headers are being dropped. They
test the path with IPv6 packets containing TCP or ICMPv6 payloads and a
Hop-by-Hop Options Header of 8 or 256 bytes. Based on the obtained re-
sults, the tool can infer what is the system causing the packet drops.

Print help information for the scan6 tool.
EXAMPLES
The following sections illustrate typical use cases of the script6
tool.
Example #1
# scan6 -i eth0 -L -e -v
Perform host scanning on the local network ("-L" option) using inter-
face "eth0" ("-i" option). Use both ICMPv6 echo requests and unrecog-
nized IPv6 options of type 10xxxxxx (default). Print link-link layer
addresses along with IPv6 addresses ("-e" option). Be verbose ("-v" op-
tion).
Example #2
# scan6 -d 2001:db8::/64 --tgt-virtual-machines all --ipv4-host
10.10.10.0/24
Scan for virtual machines (both VirtualBox and vmware) in the prefix
2001:db8::/64. The additional information about the IPv4 prefix em-
ployed by the host system is leveraged to reduce the search space.
Example #3
# scan6 -d 2001:db8::/64 --tgt-ipv4-embedded ipv4-32 --ipv4-host
10.10.10.0/24
Scan for IPv6 addresses of the network 2001:db8::/64 that embed the
IPv4 prefix 10.10.10.0/24 (with the 32-bit encoding).
Example #4
# scan6 -d 2001:db8:0-500:0-1000
Scan for IPv6 addresses of the network 2001:db8::/64, varying the two
lowest order 16-bit words of the addresses in the range 0-500 and
0-1000, respectively.
Example #5
# scan6 -d fc00::/64 --tgt-vendor 'Dell Inc' -p tcp
Scan for network devices manufactured by 'Dell Inc' in the target pre-
fix fc00::/64. The tool will employ TCP segments as the probe packets
(rather than the default ICMPv6 echo requests).
Example #6
# scan6 -i eth0 -L -S 66:55:44:33:22:11 -p unrec -P global -v
Use the "eth0" interface ("-i" option) to perform host-scanning on the
local network ("-L" option). The Ethernet Source Address is set to
"66:55:44:33:22:11" ("-S" option). The probe packets will be IPv6 pack-
ets with unrecognized options of type 10xxxxxx ("-p" option). The tool
will only print IPv6 global addresses ("-P" option). The tool will be
verbose.
Example #7
# scan6 -d 2001:db8::/64 -w KNOWN_IIDS
Perform an address scan of a set of known hosts listed in the file
KNOWN_IIDS, at remote network 2001:db8::/64. The target addresses are
obtaining by concatenating the network prefix 2001:db8::/64 with the
interface IDs of each of the addresses fund in the file KNOWN_IIDS.
Example #8
# scan6 -i eth0 -L -P global --print-unique -e
Use the "eth0" interface ("-i" option) to perform host-scanning on the
local network ("-L" option). Print only global unicast addresses ("-P"
option), and at most one IPv6 address per Ethernet address
("--print-unique" option). Ethernet addresses will be printed along
with the corresponiding IPv6 address ("-e" option).
Example #9
# scan6 -m knownprefixes.txt -w knowniids.txt -l -z 60 -t -v
Build the list of targets from the IPv6 prefixes contained in the file
'knownprefixes.txt' and the Interface IDs (IIDs) contained in the file
'knowniids.txt'. Poll the targets periodically ("-l" option), and sleep
60 seconds after each iteration ("-z" option). Print a timestamp along
the IPv6 address of each alive node ("-t" option). Be verbose ("-v" op-
tion).

script6
A tool to make complex IPv6 tasks easy script6 SCRIPT [PARAMETERS ]
root@kali:~# man script6
SCRIPT6(1) General Commands Manual SCRIPT6(1)
NAME
script6 - A tool to make complex IPv6 tasks easy script6 SCRIPT [PARAM-
ETERS]
DESCRIPTION
script6 is a set up scripts that make frequent and/or rather complex
IPv6-related tasks easy.
SCRIPTS
get-aaaa
This script takes no further arguments, and operates as follows:
+ The tool reads domain names from standard-input (one per line),
and obtains the AAAA records for the corresponding domain. If the
domain name does not contain AAAA records, the tool will add
the suffix "www.", in the hopes that the resulting domain name
might contain some.
+ Lines where the first non-blank character is the numeral sign (#)
are consdered to contain comments, and hence are ignored.
+ The format of the resulting output is:
# DOMAIN_NAME (CANONIC_NAME)
IPV6_ADDRESS_1
IPV6_ADDRESS_2
get-mx
This script takes no further arguments, and operates as follows:
+ The tool reads domain names from standard-input (oner per line),
and obtains the MX for the corresponding domain.
+ Lines where the first non-blank character is the numeral sign (#)
are consdered to contain comments, and hence are ignored.
+ The format of the resulting output is:
# DOMAIN_NAME (CANONIC_NAME)
MX_RECORD_1
MX_RECORD_2
get-ns
This script takes no further arguments, and operates as follows:
+ The tool reads domain names from standard-input (oner per line),
and obtains the NS records for the corresponding domain.
+ Lines where the first non-blank character is the numeral sign (#)
are consdered to contain comments, and hence are ignored.
+ The format of the resulting output is:
# DOMAIN_NAME (CANONIC_NAME)
NS_RECORD_1
NS_RECORD_2
get-asn6
Obtain the Origin Autonomous System (AS) number corresponding to the
specified address.
get-as6
Obtain information about the Origin Autonomous System (AS) correspond-
ing to the specified address.
get-alexa-domains
This script takes no further arguments, and operates as follows:
+ It reads from standard input lines with the same format as those
of Alexa's Top 1M web sites. That is, lines with the following syntax:
RANKING,DOMAIN_NAME
+ It extracts the domain name from each line, and prints the
corresponding domain name to standard output.
This script is typically useful for extracting domain names from
Alexa's Top 1M web sites file, such that they can be processed by other
tools (e.g. the get-aaaa command of script6).
get-trace-stats
This command causes the script6 tool to read from standard input the
results of a "script6 trace" command (typically piped from a file), and
produce statistics based on such results.
Among the statistics produced by this command are:
* Packet drop rate: That is, the percentage of destination IPv6
addresses that result unreachable if IPv6 extension headers are
employed.
* Packet drop rate by different AS: That is, the percentage of
packet
drops that occur at an Autonomous System (AS) other than the AS
corresponding to the destination IPv6 address.
* Packet drop rate by same AS: That is, the percentage of packet
drops that occur at the same Autonomous System (AS) as that
corresponding to the destination IPv6 address.
* Delta-Hops statistics: Statistics regarding the Delta-Hops at
which
the packet drops occur, with "delta-hops" defined as "the number
of
hops from the intended destination".
The get-trace-stats performs a number of sanity checks on the input
data (i.e., the output from "script6 trace"). For example, if a line of
input indicates that the last responding node for the non-EH-enabled
path6 command is not the intended destination, this means that the des-
tination is unreachable even when no IPv6 extension headers are em-
ployed, and hence the corresponding line will be discarded.
trace DESTINATION [EHTYPE[EHSIZE]] [PROTOCOL [DESTPORT]]]
The trace command causes the script6 to read IPv6 addresses from stan-
dard input (typically piped from a file). For each IPv6 address, the
script6 will try to isolate IPv6 blackholes resulting from employing
IPv6 extension headers. By default, the probe packets (containing IPv6
Extension Headers) are IPv6 packets with a Destination Options Header
of 8 bytes, encapsulating an ICMPv6 Echo Request message. However, this
can be overridden by specifying the EHTYPE {DO,HBH,FH}, EHSIZE (an in-
teger), PROTOCOL {tcp,udp,icmpv6}, and DESTPORT (a short integer) pa-
rameters.
The "trace" command of the script6 tool internally employs the path6
tool of the toolkit as follows. Let us assume that we want to isolate
an IPv6 blackhole on the path towards the destination system
2001:db8:d::1. Firstly, script6 will obtain the output of path6 towards
such destination:
1. 2001:db8:1:1000::1
2. 2001:db8:2:2000::4
3. 2001:db8:2:4000::1
4. 2001:db8:3:4000::1
5. 2001:db8:3:1000::1
6. 2001:db8:4:4000::1
7. 2001:db8:4:1000::1
8. 2001:db8:5:5000::1
9. 2001:db8:5:6000::1
10. 2001:db8:d::1
Subsequently, script6 will obtain the output of EH-enabled path6 to the
same destination:
1. 2001:db8:1:1000::1
2. 2001:db8:2:2000::4
3. 2001:db8:2:4000::1
4. 2001:db8:3:4000::1
5. 2001:db8:3:1000::1
6. 2001:db8:4:4000::1
For the sake of brevity, let us refer to the last-responding node in
the EH-enabled path6 ("2001:db8:4:4000::1" in this case) as "M". Assum-
ing both packets in both path6 commands employ the same path, we will
refer to "the node following the last responding node in the EH-enabled
path6" ("2001:db8:4:1000::1" in our case), as "M+1", etc.
Based on traceroute information above, which node is the one actually
dropping the EH-enabled packets will depend on whether the dropping
node filters packets on ingress or the egress. If the former, the drop-
ping node will be M+1. If the latter, the dropping node will be "M".
path6 assumes that nodes perform ingress-filtering. Thus, in our exam-
ple above the last responding node to the EH-enabled traceroute ("M")
is "2001:db8:4:4000::1", and therefore we assume the "node" dropping
node to be "2001:db8:4:1000::1" ("M+1").
The resulting output will have the following syntax:
DEST#LAST_NOEH#HOPS_NOEH#LAST_EH$HOPS_EH#DROPN#DROPN2
where:
* DEST: Destination IPv6 address (as read from standard input).
In our example above, this would be 2001:db8:d::1.
* LAST_NOEH: Last responding IPv6 address for the path6 command
with no IPv6 extension headers (this will be the same as DEST
if there is a working path to the destination). In our example
above, this would be 2001:db8:d::1.
* HOPS_NOEH: Number of hops to LAST_NOEH. In our example above,
this would be "10".
* LAST_EH: Last responding IPv6 address in the EH-enabled path6
command. In our example above, this would be 2001:db8:4:4000::1.
* HOPS_EH: Number of hops to LAST_EH. In our example above, this
would be "6".
* DROPN: Dropping node (M+1 in our explanation above). In our
example above, this would be 2001:db8:4:1000::1.
* DROPN: Node after the dropping node (M+2). In our example,
this would be 2001:db8:5:5000::1.
The output of the "trace" command is meant to be processed by the get-
trace-stats command of the script6 tool. Please check the blackhole6(1)
tool for a more human-friendly tool for isolating IPv6 blackholes.
EXAMPLES
The following sections illustrate typical use cases of the script6
tool.
Example #1
$ script6 get-asn 2001:db8::1
Obtain the Origin Autonomous System (AS) number corresponding to the
IPv6 address 2001:db8::1.
Example #2
$ script6 get-as 2001:db8::1
Obtain information about the Origin Autonomous System (AS) correspond-
ing to the IPv6 address 2001:db8::1.
Example #3
$ cat domains.txt | script6 get-aaaa > domains-aaaa.txt
Map the domain names contained in the file "domains.txt" into AAAA
records, and save the results in the file "domains-aaaa.txt".
Example #4
# cat domains-aaaa.txt | script6 trace do8 tcp port 25 > trace-re-
sults.txt
Find IPv6 blackholes in the path to each of the IPv6 addresses con-
tained in the file "domains-aaaa.txt" (one per line), and save the re-
sults to the file "trace-results.txt". The probe packets to be employed
are IPv6 packets with a Destination Options header of 8 bytes, encapsu-
lating a TCP segment with the Destinatio Port set to 25.
Example #5
$ cat trace-results.txt | script6 get-trace-stats
Produce statistics based on the trace results from the file "trace-re-
sults.txt" (produced with "script6 trace").
