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. :-} Cheers, -- jra -- Jay R.

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.

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. :-}
