To match an IPv4 address, the following should work (untested):
'^
([0-9]{1,2}|[01][0-9]{2}|2[0-4][0-9]|25[0-5])\.
([0-9]{1,2}|[01][0-9]{2}|2[0-4][0-9]|25[0-5])\.
([0-9]{1,2}|[01][0-9]{2}|2[0-4][0-9]|25[0-5])\.
([0-9]{1,2}|[01][0-9]{2}|2[0-4][0-9]|25[0-5])
$'
Without the line breaks, obv.
Each segment should match any number less than 256 (including zero) with 1-3 digits, including
leading zeroes.
