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