Many A-records

[Jonathan de Boyne Pollard]

f> I was once told that a network interface should have only 
f> one A-record and a corresponding PTR record. 

You were told this by someone who hadn't read RFC 2181 section 10.

f> In my world a Network interface should have one but only 
f> one A-record.
