- This is a feature. Consider what happens if you have a host called vse in
- the cs department. How would you distinguish between vse.cs.nctu.edu.tw
- and vse.cs (a host in the Prague Center of Economics, Czechoslovakia)?
- For this reason any host with a dot in the name is assumed to be fully
- qualified. Names without dots are qualified into the local domain.
-
- A partial solution is to use domaintable to map simple names to fully
- qualified names. Resolving conflicts and keeping the table up to date
- becomes painful at large sites. For those I recommend biting the bullet
- and using FQDNs.
