Thanks for the thread-link, mikeB.   8^)

However, my infile sanity-check isn't intended to parse or untaint IP addresses.   If I ever do add support for IP address input (reverse-lookups), I'll likely look to CPAN for a module.   A quick search turned up these candidates: Net::IPAddr-Find, Net::IPv4Addr, Net::IP, and NetAddr::IP.
