Both on WiFi and mobile data, DNS resolutions fail instantaneously. I can load sites by IP address in Firefox, and I can connect to other machines using SSH by IP address, but anything that requires a hostname fails.

nslookup claims to using as its name server. When I specify the server to use, such as, nslookup always fails: nslookup: can't resolve 'startpage.com'

Sometimes after rebooting DNS works for a few seconds.

This is a rooted Samsung Galaxy SIII running Cyanogenmod 11 nightly build, Android version 4.4.4. The problem was the same on SlimKat.

  • When did the problem start? Was it as soon as you installed a custom ROM? Have you installed an ad-blocker, firewall, or similar?

  • I flashed an update to CyanogenMod and the problem is gone for now.

  • If the problem is solved, you should answer your own question so it no longer shows up as unanswered. CM nightly builds commonly have problems like this: that's why they're not recommended for everyday use.

The problem disappeared when a newer CyanogenMod build was flashed.

(The problem was present on a stable SlimKat ROM as well.)
