Method normalize_addr_basic

  `string normalize_addr_basic(string addr)`

Description

  Normalizes a formatted IPv6 address to a string with eight hexadecimal numbers separated by `":"`. addr is given on the same form, or any of the shorthand varieties as specified in RFC 2373, section 2.2.

  All hexadecimal letters in the returned address are lower-case, and there are no superfluous leading zeroes in the fields.

  Zero is returned if addr is incorrectly formatted.
