Most likely, yes.  Just to be safe, I would do something like

nslookup [ip-address] [isps-nameserver]

to make sure that you're getting the query from your ISPs name server and
not from the one on your network (although if you have your network DNS
set up correctly it shouldn't make a difference.)
