It's a DNS query. You need to be able to do DNS resolution.

If your MS/SA machine is it's own resolving server, then it needs to be
able to query to arbitrary DNS servers.

If your MS/SA machine uses another server for resolution it needs to be
able to talk to that DNS server, and that DNS server needs to be able to
talk to query DNS servers.

You can tell what machine is being used as a resolver by looking at
/etc/resolv.conf. A machine that's it's own resolver will have "localhost"
