are you just guessing this or do you have any evidence of a nameserver
which has the wrong information?

it looks to me like one of YOUR nameservers has the wrong information
somehow.

so it's the record for 'vermont.websoft.com' that's inconsistent:
perhaps one of your glue records is messed up?  i'd do a bit of poking
around in your zone files; maybe grep for the invalid IP address if you
can't figure out where it's coming from.
