adding to that: dotted hex IPv4 0x12.0xab.0xcd.0xef. single hex number
0x12abcdef, or a single decimal number. these used to work on Firefox
3.x (at least - may be they changed it in more recent releases).

but i don't think that it is a serious fault. a simple pattern match
will detect it.

i personally like rare IPv4 URLs as considering an email with rare
IPv4 URLs as spam results in 0% false positives :). while considering
a dotted decimal IPv4 as spam results in  3-4% false positives. (stats
from my data set).
