This is a private interconnect between Sprint and MCI, and the serial
subnet comes out of address space assigned to MCI (so the inverse
mapping is handled by MCI as well). We didn't really know what map
the inverse address to in the PTR record, but we wanted it to have
*some* mapping, so we just picked an arbitrary hostname.

We'd be happy to change this mapping to some other hostname (or CNAME
the inverse address), if the Sprint folks would prefer something
different :-)

The other end of the link has a more-descriptive DNS entry:

roy@ns% host -t ptr 89.77.157.206.in-addr.arpa
89.77.157.206.in-addr.arpa PTR core4-hssi5-0.WillowSprings.mci.net

BTW, core4.wsp.mci.net did not show up in the traceroute
due to a bug in the code that we are running. (The bug
has been fixed in a later version.)

The direct interconnection between MCI and Sprint is in
the Chicago area rather than in Denver. The connection
speed is OC12 rather than DS3 :-)

Is this optimistic or are there really more than 4 DS3s on both sides
feeding the routers? I'm not complaining, just curious.

Well, I wanted to name our private peerings after the
seven deadly sins, but maybe "somerouter.sprintlink.net"
is a good choice until the names are settled on this side.

That'll happen when the tactical build-out we began a week
and a half ago is completed in a few days.

Meanwhile, 206.157.77.90 is sl-chi-15-H1/0-T3.sprintlink.net (anger)
206.157.77.34 is sl-dc-1-H5/0-T3.sprintlink.net (sloth)
and 206.157.77.66 is sl-stk-1-H9/0-T3.sprintlink.net (pride)

which are subject to move, and the mapping for the
remaining RRs are not nearly as firm...

Of course, I like Enke's suggestion too. :-)

Sean.

Yah, but once you use Cook, Metcalfe, Bass, Fleming, Metzger, Denninger,
and Dillon, how do you name the rest?

And someone from another provider (than Sprint) will have to use
smd-hatesflaps-h3/0.me.net

Hmm...

Do the routers at both ends actually think it's OC12?

there are two oc-3 circuits feeding the pop on our side.
btw. it was a joke it's a ds-3 interconnect.

Sorry, it was a joke (read ":-)") in replying to the original
question "what kind link it is". Doing OC12 between routers
is still a dream today ...

Depends on your routers now doesn't it?
I don't think that commodity routers are
there yet, but products exist that claim
(and charge) for OC12.

Yes, there are products that claim to do OC-12, but they do not work. Then
there are router that can do OC-12, but the the software needs a LOT of
work (a few years).

Mea culpe... I mistook it for "marketing announcement"
(i.e. tied to reality only in theory... ;-)

Oh, tish and tosh. Think of it as an opportunity to announce
the OC24c connections between Sprintlink and BBN Planet.

Well, there are OC12 backbones that are being built today.
It will not be long before we see OC12 between providers.
Sometimes next year?

Or someone can announce OC192 at a NAP. Maybe it'll even make a trade
rag. ;-)
