Creates the NormalizeAddr Func to Format IPv6 Addresses

[kheina]

NormalizeAddr takes an address as a string and returns a normalized copy. If the address is a URL, IP Address, or host:port address that includes an IPv6 address, the normalized copy will be conformant with RFC-5952 §4. If the address cannot be parsed, an error will be returned.

There are two valid formats:

• hosts: host
  • may be any of: IPv6 literal, IPv4 literal, dns name, or [sub]domain name
  • IPv6 literals are not required to be encapsulated within square brackets
    in this format
• URIs: [scheme://] [user@] host [:port] [/path] [?query] [#frag]
  • format should conform with RFC-3986 §3 or else the returned address may be parsed and formatted incorrectly
  • hosts containing IPv6 literals MUST be encapsulated within square brackets, as defined in RFC-3986 §3.2.2 and RFC-5952 §6
  • all non-host components are optional

See:

• RFC-5952
• RFC-3986
