Click on the ip-number! Rated 5 out of 5 stars
Well, showing the ip-numbers is nice, but its real strength is there when you click on the ip-number. Lots of hidden goodies there:
leftclick on the ip-address and you can do a lot of operations on the hostname, rightclick and you can explore the ip-address.
You can add your own sites or your local programs to the list. It took me some headache to get a local program working. Finally the auther hinted me: the program needs to open an own window. So just adding !/usr/bin/whois doesn't work, you need to write some wrapper around it.So I came up with shell-scripts like this one:
/usr/bin/xterm -rv -T "whois $1" -e "whois $1 | less" &
Conclusion: a very flexible and convenient tool for checking out (problems with) websites, anything you would open a terminal for is now one click away!
