I'm not sure when this started, but recently Cygwin has been unable to
resolve (certain) hostnames.

--2015-07-22 15:17:04--
Resolving ( failed: Non-recoverable failure
in name resolution.
wget: unable to resolve host address ‘’

happens for SSH as well (I'm aware I probably can't ssh to,
but it doesn't fail there, it fails during name resolution)
ssh: Could not resolve hostname Non-recoverable failure in
name resolution

however, I can get to in the browser sitting next to the
cygwin window just fine.
ping (from windows, but inside cygwin) also works...

Pinging [] with 32 bytes of data:
Reply from bytes=32 time=43ms TTL=128

Interestingly enough, DOES resolve correctly.

No hostname other than that I've tried resolves at all
unless it is defined in my Windows hosts file.

I've searched google, the mailing lists, and the faq in vain.

Any ideas?
