Shodan is currently running a sale for its membership for just $4 lifetime (normally $49) to celebrate their 4 million user. A great tool for monitoring your IPs in addition to its searching capabilities. I think the sale will expire in 4 hours, a few hours left. This is the best time to grab one if you want it.
@beagle sweet deal seems to work, they at least took my $4 !
I do recall first coming across shodan to discover to my horror how many IP cams are on the net, after having just setup cams in my home !
