IPv6-Regex Chris Warwick, @cjwarwickps, October 2015 This PowerShell script tests a number of regular expressions that match text representations of IPv6 addresses. The script also runs the sample test cases against the [System.Net.IpAddress]::TryParse() method to illustrate some subtle considerations with address validation. See the end of the script for further notes. Script Structure ---------------- This script is split into four sections: 1. The first section defines an IPv6 regex to the tested against a set of sample addresses. A number of other Regexs gathered from across the web are also defined here. 2. Following the regex definitions, an array of test script-blocks is defined. Each script block takes a test IPv6 address as a parameter and tests this address against a specific regex or against the IpAddress.TryParse() method. The script blocks return true if the address is considered valid by the test or false otherwise. 3. The next (largest) section of the script defines sample IPv6 addresses to be tested. There are a large number of both valid and invalid address representations defined. 4. The final section of the script runs the tests. Each test script block is selected in turn and the test addresses are matched against the script blocks. Each test returns a test result object containing details of the individual test. The tests are timed to allow comparison of the performance of each test method (use the -Verbose switch to view timings). NOTE: The output of this script is most useful as a consolidated report. Consequently, the script 'breaks the rules' somewhat by including output formatting. This behaviour can be changed by specifying the '-NoFormat' switch parameter to instruct the script to pass test- result objects to the output pipeline (these can then be formatted or collected as required). Results ------- Unsurprisingly, a number of regexs found on the web are invalid (only one is included here, others have been omitted). Beware of using random regexs without testing them. There are some subtleties with the operation of the IpAddress.TestParse() method. 1. Both the regex and the IpAddress.TryParse() methods allow leading zeroes in the IPv4 octets. This is actually explicitly invalid in the definition in rfc3986 (apparently some systems (?) use a leading zero to denote an Octal number in the IPv4 Octet). 2. The IpAddress::TryParse method does not accept leading elided-zeroes syntax: ('::....') if there is only one group (the first group) of the address mising - although this is valid according to the RFC. So, for example, ::2:3:4:5:6:7 is considered valid by IpAddress::TryParse, but ::2:3:4:5:6:7:8 isn't 3. The IpAddress.TryParse() method by default accepts IPv4 addresses; these are qualified (filtered out) by checking the address against the [System.Net.Sockets.AddressFamily]::InterNetworkV6 type Compiling regexs is an expensive operation, and even for the relatively large number of tests defined here the investment is not warranted. Although the IpAddress.TryParse() method has some idiosyncrasies it may be preferred to the regex matching methods given the complexity of these regexs (IpAddress.TryParse is probably equally as complex but the complexity is at least hidden :-) #> Function IPv6Regex { <# .SYNOPSIS Tests IPv6 Regex patterns against a large number of sample test addresses. .DESCRIPTION This function tests a number of IPv6 regexs against a selection of valid and invalid IPv6 addresses to verify that the regexs perform as expected. The function also tests the sample addresses using the [System.Net.IpAddress]::TryParse() method to illustrate the performance and conformance of this method. .NOTES The script will time the relative performance of the various regexs; use the -Verbose switch to display the timimg information. .PARAMETER TestName If specified, only run tests with names matching this. .PARAMETER NoFormat Provide raw output objects for each test. The default is to select only failing test result objects and to format the resulting output. Use this parameter if you wish to use a different selection or formatting option to the default provided here. .EXAMPLE IPv6Regex Run all tests and display those that fail. .EXAMPLE IPv6Regex -Verbose Run all tests; additionally display relative performance timings. .EXAMPLE IPv6Regex -TestName 'compiled' Only run tests where the test name includes the string 'compiled'. .EXAMPLE IPv6Regex -NoFormat Run all tests and output a raw RegexMatchResult object for each test. .INPUTS None .OUTPUTS By default, outputs formated table of failing tests. Use -NoFormat to output raw objects. .FUNCTIONALITY Test IPv6 Regexs against sample IPv6 Addresses. .LINK http://github.com/ChrisWarwick/IPv6Regex #> [OutputType('RegexMatchResult')] [CmdletBinding()] Param ( $TestName, # Only run tests with names matching this (default = run all tests) [Switch]$NoFormat # Don't format the output (just retun TestResult objects) ) #region Script Section 1.

This script is inspired by a Perl script from here: http://download.dartware.com/thirdparty/test-ipv6-regex.pl However, some of the regexs are new or significantly refactored. A large number of the test address cases are taken from this site of from others sites linked from this page. Overview: The regex matches the following IPv6 address forms. Note that these are all the same address: fe80:0000:0000:0000:0204:61ff:fe9d:f156 -- full form of IPv6 fe80:0:0:0:204:61ff:fe9d:f156 -- drop leading zeroes fe80::204:61ff:fe9d:f156 -- collapse multiple zeroes to :: in the IPv6 address fe80:0000:0000:0000:0204:61ff:254.157.241.86 -- IPv4 dotted quad at the end fe80:0:0:0:0204:61ff:254.157.241.86 -- drop leading zeroes, IPv4 dotted quad at the end fe80::204:61ff:254.157.241.86 -- dotted quad at the end, multiple zeroes collapsed In addition, the regular expression matches these IPv6 forms: ::1 -- localhost fe80:: -- link-local prefix 2001:: -- global unicast prefix Link Local addresses may have a Scope-ID (or Zone Index) at the end of the address following a percent sign. The Scope Id will be the adapter index (in Windows). The Scope ID is used to distinguish between multiple similar link local addresses on different interfaces. http://msdn.microsoft.com/en-us/library/aa921042.aspx The regex here can test for Scope IDs, but this is currently commented out of the regex (see code below) See http://www.ietf.org/rfc/rfc4291.txt "IP Version 6 Addressing Architecture" Section 2.2 "Text Representation of Addresses" (An extract of this section of the RFC is included at the end of this script) ...and http://tools.ietf.org/html/rfc5952 (Updates rfc4291) Also see: http://www.ietf.org/rfc/rfc3986.txt "Uniform Resource Identifier (URI): Generic Syntax" Section 3.2.2 Syntax Components - Host (An extract of this section of the RFC is included at the end of this script) And: http://tools.ietf.org/html/rfc4007 "IPv6 Scoped Address Architecture" http://en.wikipedia.org/wiki/IPv6_address Todo: Add -StrictIPv4 switch (for leading 0 in IPv4 Octet) #------------------------------------------------------------------------------ Further Background: There are a number of RFCs covering IPv6 formats. Some relevent extracts are included here: From http://www.ietf.org/rfc/rfc4291.txt "IP Version 6 Addressing Architecture" 2.2. Text Representation of Addresses There are three conventional forms for representing IPv6 addresses as text strings: 1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are one to four hexadecimal digits of the eight 16-bit pieces of the address. Examples: ABCD:EF01:2345:6789:ABCD:EF01:2345:6789 2001:DB8:0:0:8:800:200C:417A Note that it is not necessary to write the leading zeros in an individual field, but there must be at least one numeral in every field (except for the case described in 2.). 2. Due to some methods of allocating certain styles of IPv6 addresses, it will be common for addresses to contain long strings of zero bits. In order to make writing addresses containing zero bits easier, a special syntax is available to compress the zeros. The use of "::" indicates one or more groups of 16 bits of zeros. The "::" can only appear once in an address. The "::" can also be used to compress leading or trailing zeros in an address. For example, the following addresses 2001:DB8:0:0:8:800:200C:417A a unicast address FF01:0:0:0:0:0:0:101 a multicast address 0:0:0:0:0:0:0:1 the loopback address 0:0:0:0:0:0:0:0 the unspecified address may be represented as 2001:DB8::8:800:200C:417A a unicast address FF01::101 a multicast address ::1 the loopback address :: the unspecified address 3. An alternative form that is sometimes more convenient when dealing with a mixed environment of IPv4 and IPv6 nodes is x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values of the six high-order 16-bit pieces of the address, and the 'd's are the decimal values of the four low-order 8-bit pieces of the address (standard IPv4 representation). Examples: 0:0:0:0:0:0:13.1.68.3 0:0:0:0:0:FFFF:129.144.52.38 or in compressed form: ::13.1.68.3 ::FFFF:129.144.52.38 2.3. Text Representation of Address Prefixes The text representation of IPv6 address prefixes is similar to the way IPv4 address prefixes are written in Classless Inter-Domain Routing (CIDR) notation [CIDR]. An IPv6 address prefix is represented by the notation: ipv6-address/prefix-length where ipv6-address is an IPv6 address in any of the notations listed in Section 2.2. prefix-length is a decimal value specifying how many of the leftmost contiguous bits of the address comprise the prefix. For example, the following are legal representations of the 60-bit prefix 20010DB80000CD3 (hexadecimal): 2001:0DB8:0000:CD30:0000:0000:0000:0000/60 2001:0DB8::CD30:0:0:0:0/60 2001:0DB8:0:CD30::/60 The following are NOT legal representations of the above prefix: 2001:0DB8:0:CD3/60 may drop leading zeros, but not trailing zeros, within any 16-bit chunk of the address 2001:0DB8::CD30/60 address to left of "/" expands to 2001:0DB8:0000:0000:0000:0000:0000:CD30 2001:0DB8::CD3/60 address to left of "/" expands to 2001:0DB8:0000:0000:0000:0000:0000:0CD3 When writing both a node address and a prefix of that node address (e.g., the node's subnet prefix), the two can be combined as follows: the node address 2001:0DB8:0:CD30:123:4567:89AB:CDEF and its subnet number 2001:0DB8:0:CD30::/60 can be abbreviated as 2001:0DB8:0:CD30:123:4567:89AB:CDEF/60 #------------------------------------------------------------------------------ From: http://www.ietf.org/rfc/rfc3986.txt "Uniform Resource Identifier (URI): Generic Syntax" Section 3.2.2 Syntax Components - Host A 128-bit IPv6 address is divided into eight 16-bit pieces. Each piece is represented numerically in case-insensitive hexadecimal, using one to four hexadecimal digits (leading zeroes are permitted). The eight encoded pieces are given most-significant first, separated by colon characters. Optionally, the least-significant two pieces may instead be represented in IPv4 address textual format. A sequence of one or more consecutive zero-valued 16-bit pieces within the address may be elided, omitting all their digits and leaving exactly two consecutive colons in their place to mark the elision.
