[fpc-pascal] Getting (local) domain info from DNS

[Mark Morgan Lloyd]

Is there a straightforward way of getting the SOA information for a 
specific domain, typically the local one, from a DNS server?

As background, I'm looking for a way to perform a reasonable check of 
the health of the local LAN, before trying to recover from a database 
error caused either by a physical network problem or by server failure. 
I can't speak for other types of connection, but 
TPQConnection.Connected:=FALSE will sit there indefinitely if the 
Ethernet plug is pulled out from the back of the computer.
