They probably want that so they know where to route the ticket.  I
pointed them at
  https://tools.ietf.org/html/rfc4890#page-14
and suggested they have someone on the network team use ipv6 to
connect to pay.gov over a 1280 byte MTU link.  Hopefully that's enough
to get the ticket routed to the correct group.

And thanks for being willing to work with them to fix the problem.
