Perlmonks meta-wisdom

Dear Wise Monks,

This is a question about perlmonks.org itself. Why do I get multiple IP addresses in the following nslookup query? (What does it mean?? It it a round-robin setup? Can it occur with DNS propagation delay?)

> nslookup www.perlmonks.org
;; Got recursion not available from ###.##.#.6, trying next server
;; Got recursion not available from ###.##.#.14, trying next server
Server: 4.2.2.2
Address: 4.2.2.2#53

Non-authoritative answer:
www.perlmonks.org canonical name = perlmonks.org.
Name: perlmonks.org
Address: 209.197.123.153
Name: perlmonks.org
Address: 216.92.34.251
Name: perlmonks.org
Address: 66.39.54.27

I've redacted the DNS server info to protect the identity of my employer. Thanks!

    Because there are three servers serving the site? Load balancing and redundancy and whatnot?

      Thanks -- that's what I thought. I guess some kind of "choose one at random" scheme.
