DNS resolver addresses for Sprint PCS/3G/4G

I've noticed, for quite some time, that there seems to be a specific category
of slow that I see in using apps on my HTC Supersonic/Sprint EVO, on both
their 3G and 4G networks, and I wonder if it isn't because the defined
resolvers are 8.8.4.4 and 8.8.8.8, which aren't *on* Sprint's networks.

Does anyone have, in their magic bag of tricks, IP addresses for resolvers
that *are* native to that network, that they wouldn't mind whispering in my
ear?

I don't suppose Android's smart enough to swap that file around when the
IP core notices the uplink has changed? (Yes, I know, that's properly a
question for XDA-Devel...)

Offlist is fine. Yes, I owe the list summaries on a couple earlier
questions; I still have the details to write from. :-}

doesn't sprint intercept all udp/53 on their cellular network?

I don't know. If they do, and said boxes are slow, that could explain it,
too. On the gripping hand, I am running Cyanogen, which isn't Sprint
specific, and that could explain it too.

Not directly PCS, but ns[1-3].sprintlink.net are used for their recursive DNS for customers. They're anycasted so you should be able to just use the first IP (204.117.214.10). I don't know what these are because I haven't been a customer for years, but it appears they may have servers specific to PCS as well:

PING ns1.sprintpcs.net (69.43.160.200) 56(84) bytes of data.
rdrake@terminal:~$ host ns2.sprintpcs.net
ns2.sprintpcs.net has address 69.43.160.200
rdrake@terminal:~$ host ns3.sprintpcs.net
ns3.sprintpcs.net has address 69.43.160.200

well, at least one server.

Except:

69.43.160.200 traces through to an XO customer in California:

Castle Access Inc ARIN-CASTLE-ALLOC (NET-69-43-128-0-1) 69.43.128.0 - 69.43.207.255

Perhaps they do some "special" things on the PCS side to make this DNS server work.

I would use 204.117.214.10.
