DNS allows more than one IP address to be associated with a single FQDN. Typicaly proactice now is to do a gethostbyname(), look at the first IP address, and fail if you can't talk with it. We want client writers to be a little more tenacious in this. Keep the list of addresses, try one. If it fails try another. Keep doing that until you succeed or run out of IP addresses. -- Ron Daniel Jr. email: email@example.com Advanced Computing Lab voice: (505) 665 0597 MS B287 fax: (505) 665 4939 Los Alamos National Laboratory http://www.acl.lanl.gov/~rdaniel/ Los Alamos, NM 87545 tautology:"Conformity is very popular"
