Please let me know is it possible through boost or not.
Apologies, I missed that message.

I don't see how any of the alternatives in that regular expression can match the string you give: the only alternative that could possibly match appears to be the "|(::([0-9A-Fa-f]{1,4}:){0,6}[0-9A-Fa-f]{1,4})" part, but that can't match because your string uses "." as a separator between numbers, where as the expression only works with ":" as a separator. Which part of the regex did you expect should match? Also did you intend the \b's to be literal bell characters, or \\b's and hense regular expression operators (word boundaries)? HTH, John.
