I decided before moving on with the DNS tools, I will read a bit more about the protocol. Till then I check a few from the miscellaneous tools. There is a utility called ipcalc, which is really a subnet calculator, as the name suggest. We give an IP and a mask, and it prints out every useful information, like number of hosts, broadcast IP, etc... If you send a few years in networking you probably won't need this :-)

If we give a second mask, then it will either split or create a supernet subnet. Here is an example:

ipcalc /8

The result is really colorful :-) I like it, but you can turn it off if you want.
