Maybe because DNS rev (IP -> HOSTNAME).
I don't know the details...but my experi
ence is...
When you use ip to connect another compu
ter, it need to check if this ip is ille
gal and check if this ip is from the rig
ht one.
So linux default is set to find the host
name from HOSTS -> DNS -> NIS
If you add IP to /etc/hosts, then it can
find the hostname from the IP...and need
n't DNS.
