You don't have to rely on "one NIS server". You can have as many NIS
servers as you want; if one fails, its clients will switch to another one.

It's not done by the NIS master server, it's done by whichever NIS server
the client asks. And it may result in fewer DNS queries, since all the
clients of that server will share its cache. If resolving were done on the
clients, each client would have to query for the same host.
