NAME
addr6 - An IPv6 address analysis and manipulation toolSYNOPSIS
addr6 [-a IPV6_ADDR -i] [-d] [-d] [-q] [-s] [-j PREFIX] [-b TYPE] [-k SCOPE] [-w UNICAST_TYPE] [-g IID_TYPE] [-J PREFIX] [-B TYPE] [-K SCOPE] [-W UNICAST_TYPE] [-G IID_TYPE] [-v] [-h]DESCRIPTION
addr6 is an IPv6 address analysis tool tool. It can employed identify the address type/scope, and infer the type of Interface ID employed by an IPv6 address. Additionally, addr6 can also produce statistics about a set of IPv6 addresses.OPTIONS
addr6 takes its parameters as command-line options. Each of the options can be specified with a short name (one character preceded with the hyphen character, as e.g. "-i") or with a long name (a string preceded with two hyphen characters, as e.g. "--stdin").- -a IPV6_ADDRESS, --address IPV6_ADDRESS
- This option ca be employed to specify a single IPv6 address that is meant to be processed by the tool. This option is typically employed in conjunction with the '-d' tool, to decode the IPv6 address in question.
- -i, --stdin
- This option request the tool to read IPv6 addresses from standard input (stdin), until an EOF (End-Of-File) condition is found.
- -j PREFIX, --accept PREFIX
- Accept IPv6 addresses belonging to the specified IPv6 prefix (PREFIX/LEN).
- -b TYPE, --accept-type TYPE
-
Accept IPv6 addresses belonging to the specified address type. Valid address
types are:
* unicast

address scopes are:
* reserved
* interface (or "interface-local)

* admin (or "admin-local")
* site (or "site-local")
* admin (or "admin-local")
* organization (or "organization-local")
* global

* unspecified
- -w UNICAST_TYPE, --accept-utype UNICAST_TYPE
-
Accept IPv6 addresses belonging to the specified unicast type. Valid unicast
address types are:
* loopback
* ipv4-compat
* ipv4-mapped
* link-local
* site-local
* unique-local
* 6to4
* teredo
* global
- -g IID_TYPE, --accept-iid IID_TYPE
-
Accept unicast IPv6 addresses with an Interface ID of the specified type.
Valid Interface ID types are:
* ieee
* isatap
* ipv4-32
* ipv4-64
* ipv4-all
* embed-port
* embed-port-rev
* embed-port-all
* low-byte
* byte-pattern
* random
- -J PREFIX, --block PREFIX
- Block IPv6 addresses belonging to the specified IPv6 prefix (PREFIX/LEN).
- -B TYPE, --block-type TYPE
-
Block IPv6 addresses belonging to the specified address type. Valid address
types are:
* unicast
* unspec
* multicast
- -K SCOPE, --block-scope SCOPE
-
Block IPv6 addresses belonging to the specified address scope. Valid address
scopes are:
* reserved
* interface (or "interface-local)
* link (or "link-local")
* admin (or "admin-local")
* site (or "site-local")
* admin (or "admin-local")
* organization (or "organization-local")
* global
* unassigned
* unspecified
- -W UNICAST_TYPE, --block-utype UNICAST_TYPE
-
Block IPv6 addresses belonging to the specified unicast type. Valid unicast
address types are:
* loopback
* ipv4-compat
* ipv4-mapped
* link-local
* site-local
* unique-local
* 6to4
* teredo
* global
- -G IPV6_ADDRESS, --block-iid IID_TYPE
-
Block unicast IPv6 addresses with an Interface ID of the specified type.
Valid Interface ID types are:
* ieee
* isatap
* ipv4-32
* ipv4-64
* ipv4-all
* embed-port
* embed-port-rev
* embed-port-all
* low-byte
* byte-pattern
* random
- -q, --print-unique
- This option causes the tool to eliminate duplicate addresses from the list of IPv6 addresses read from standard input (stdin). That is, when reading a list of addresses from stdin, only the first "copy" of each address will be processed by the tool (with later ones being simply ignored).
- -c, --print-canonic
- This option request the tool to print the IPv6 address specfied with the '-a' option (or a list of addresses read froom stdin if the '-i' option was set) in its canonic form. This is useful to before comparing textual representations of IPv6 addresses, since the same address can usually be written in multiple different ways.
- -d, --print-decode
-
This option request the tool to decode the IPv6 address specfied with the
'-a' option (or a list of addresses read froom stdin if the '-i' option
was set). The current version of the tool supports only decode type, in
which information is printed for each address with the following syntax:
AddressType=AddressSubtype=Scope=IIDType=IIDSubtype This simple syntax is meant to be easy for scripting purposes. Future versions of the tool will incorporate a human-friendly mode.
- -s, --print-stats
-
This option requests the tool to produce address statistics from the list of
IPv6 addresses read from standard input. This option should be used in
conjunction with the '-i' option, such that multiple addresses can be
given as input to addr6.
addr6 will always print the total number of IPv6 addresses that have been
examined, and the percentage of unicast, multicast, and unspecified (::)
addresses. If at least one unicast address is identified, unicast-specific
statistics will be printed. In the same way, if at least one multicast
address is identified, then multicast-specific statistics will be printed.
Unicast-specific statistics include:
1) Number and percentage of each unicast address type (global
unicast, link-local unicast, 6to4, Teredo, etc.).
2) Number and percentage of each of the different Interface
ID types (IEEE-based, low-byte, etc.). Only those unicast address types for which there are multiple possible types of Interface-IDs will be considered for the Interface-ID assessment. Namely,
* 6to4
* Global Unicast
* Link-local Unicast
* Site-local unicast addresses (deprecated)
* Unique local unicast addresses Unicast address types such as 'Teredo' are not considered by this analysis, since they have a single type of Interface-ID, as specified by the corresponding specifications. Multicast-specific statistics include:
1) Number of addresses and percentage of each multicast
address type (Permanent, Embedded-RP, etc).
2) Number addresses and percentage of each of the multicast
address scope different Interface ID types (Link, Interfa-
ce, Global, etc.)
- -v, --verbose
- This option selects the "verbosity" of the tool. If this option is left unspecified, only minimum information is printed.
- -h, --help
- Print help information for the addr6 tool.
EXAMPLES
The following sections illustrate typical use cases of the addr6 tool.Note: In this particular scenario, the address list results
from the command 'cat addresslist.txt', that has its output
redirected to the standard input of the addr6 tool.
