It turns out to be much worse than this.  With dhclient at least I
should have been able to figure out the netblk.  Turns out there is no
"netblk," not if you as I do think of netblks as contiguous, maskable
address ranges.  They're apparently random IPs spread amongst gtei's /20

Alas, the provided Fujitsu replacement, an Orckit DSL device, doesn't
do IP routing.  Ethernet bridging seems all it's capable of.  This
causes other problems when the provider's DHCP server (an NT
box)(sigh) takes a dump and forgets about my lease even though it's
been only 3600 seconds instead of the granted 432000, or simply
ignores my bootp requests as it has been doing since 11am on Friday.

I asked, they said they have no capability for static routing or IPs
"at this time."  I'm not going to push it right now since they're
obviously swamped in getting someone to reboot their NT box to get the
dhcp server fixed.  Seems it takes GTEI from Friday afternoon until
(projected, promised) sometime before 2PM on Tuesday to do this.

I'm guessing the discman-like Fujitsu bridge is targetting the home
market: Not only doesn't it fit in a rack, it's not even rectangular,
therefore it doesn't stack well with all the other garbage in the
equipment closet.

It would be very nice to have but seeing how much I've paid for
FreeBSD I'm going to be hard pressed to criticize volunteers for not
taking legal risks :-)
