If those headers are forged, it is an expert forgery.

The MX hosts for the net.insp.irs.gov domain are fun:
net.insp.irs.gov        preference = 10, mail exchanger = tcs-gateway2.treas.gov
net.insp.irs.gov        preference = 20, mail exchanger = tcs-gateway1.treas.gov
net.insp.irs.gov        preference = 30, mail exchanger = gotcha.treas.gov
irs.gov nameserver = gotcha.treas.gov
irs.gov nameserver = nis.ans.net
irs.gov nameserver = ns.ans.net
tcs-gateway2.treas.gov  internet address = 204.151.246.2
tcs-gateway1.treas.gov  internet address = 204.151.245.2
gotcha.treas.gov        internet address = 204.151.246.80

`gotcha.treas.gov'?  It's a real host connected through ans.net ...

Except for hop 16, this is the same traceroute as to
tcs-gateway2.treas.gov.  For what it's worth, the traceroute to
tcs-gateway1 is slightly different:
