Resolving hostnames via hosts file could be significantly faster than using the router's DNS server. > > It's not one hosts file on every > > machines on the network, it's one hosts file with every machines on > > the LAN registered in it on one of the node on the LAN. > > … which just means there are two machines needing the up-to-date hosts > file: the server-PC that avoids disturbing the router, and the router > running a DNS server. Still one more than necessary? In the classic client-server topology the server doesn't need the complete hosts file. Only the client(s) need(s) an entry for the server in the(ir) hosts file[1]. Exception would be of course, if the service provided by the server requires accessing other systems (backup server?).
