If you want it really tight, how about something along these lines:

INT8: ([01]?[0-9]?[0-9]|2([0-4][0-9]|5[0-5]))
IPADDR: {INT8}\.{INT8}\.{INT8}\.{INT8}

These are fine with me, I hacked this up pretty quick and I'm not really
aware of [f]lex interfaces.

I'm just wondering if we could reduce the lexer.c code size without
sacrificing too much speed. lexer.c is >46,000 lines here, which pretty
much stinks.
