Or set up local DNS and search domains, or even just add entries to your hosts file. `ssh fw` is easy, as is `ssh server`, which while more characters are more in the central typing plane.
I have those too, but I'm familiar with all the IPs and I just got tired of adding DNS entries. Esp for some predictable ones in the "dynamic" range.
Also there are times I don't have DNS working. Often times at some console where copy/paste also isn't working or where I don't even have a mouse, and I extra appreciate the simpler typing :)
