colon :: Text -> Maybe IPv6AddrToken

doubleColon :: Text -> Maybe IPv6AddrToken

sixteenBits :: Text -> Maybe IPv6AddrToken

ipv4Addr :: Text -> Maybe IPv6AddrToken

expandTokens :: [IPv6AddrToken] -> [IPv6AddrToken]

maybeIPv6AddrToken :: Text -> Maybe IPv6AddrToken

Returns Just one of the valid IPv6AddrToken, or Nothing.

maybeIPv6AddrTokens :: Text -> Maybe [IPv6AddrToken]

Returns Just a list of IPv6AddrToken, or Nothing.

ipv4AddrToIPv6AddrTokens :: IPv6AddrToken -> [IPv6AddrToken]

Rewrites Just an embedded IPv4Addr into the corresponding list of pure IPv6Addr tokens.

 ipv4AddrToIPv6AddrTokens (IPv4Addr "127.0.0.1") == [SixteenBits "7f0",Colon,SixteenBits "1"]

ipv6TokensToText :: [IPv6AddrToken] -> Text

Given an arbitrary list of IPv6AddrToken, returns the corresponding Text.

ipv6TokensToIPv6Addr :: [IPv6AddrToken] -> Maybe IPv6Addr

isIPv6Addr :: [IPv6AddrToken] -> Bool

Returns True if a list of IPv6AddrToken constitutes a valid IPv6 Address.

maybeTokIPv6Addr :: Text -> Maybe [IPv6AddrToken]

This is the main function which returns Just the list of a tokenized IPv6 address text representation validated against RFC 4291 and canonized in conformation with RFC 5952, or Nothing.

maybeTokPureIPv6Addr :: Text -> Maybe [IPv6AddrToken]

Returns Just the list of tokenized pure IPv6 address, always rewriting an embedded IPv4 address if present.

fromDoubleColon :: [IPv6AddrToken] -> [IPv6AddrToken]

toDoubleColon :: [IPv6AddrToken] -> [IPv6AddrToken]

networkInterfacesIPv6AddrList :: IO [(String, IPv6)]
