... why would you want a random external IP address? I can think of lots of reasons, but none of them are good ones -- like checking for an open mail relay to send your spam through, or directing your script-kiddie exploit tool against...	[reply]

The only potentially good reason I can think of is to test your IP-matching regexen. That is, if you're against using Regexp::Common::net.	[reply]

Actually, I have a legitimate use for this. I want to compare the accuracy of two competing products, which are essentially large ip range databases. I have both in my DB now, and am writing a script to perform lookups on a large number of random IPs. I am examining those cases where the results do not line up.	[reply]

Various ways using various mysteriously named functions from various mysteriously named packages, but it's easy enough with pure perl: `## Subs to convert dotted-quads to integers and vice versa sub dq2n{ unpack 'N', pack 'C4', split '\.', $_[ 0 ] };; sub n2dq{ join '.', unpack 'C4', pack 'N', $_[ 0 ] };; $start = dq2n( '71.100.100.180' );; print n2dq( $_ ) for $start .. $start + 100;; 71.100.100.180 71.100.100.181 71.100.100.182 ... 71.100.100.254 71.100.100.255 71.100.101.0 71.100.101.1 71.100.101.2 ... 71.100.101.22 71.100.101.23 71.100.101.24` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Random sampling in a certain ip range is one reason...	[reply]
