 A.4.4 Addresses
 ---------------
 
 IPv4 Address
      `(([[:digit:]]{1,3}"."){3}([[:digit:]]{1,3}))'
 
 IPv6 Address
 
      hex4         ([[:xdigit:]]{1,4})
      hexseq       ({hex4}(:{hex4}*))
      hexpart      ({hexseq}|({hexseq}::({hexseq}?))|::{hexseq})
      IPv6address  ({hexpart}(":"{IPv4address})?)
 
      See RFC2373 for details.
 
 URI
      `(([^:/?#]+):)?("//"([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?'
 
      This pattern is nearly useless, since it allows just about any
      character to appear in a URI, including spaces and control
      characters.  See RFC2396 for details.
