If I ping localhost, I receive a reply from ::1 which IIRC is the IPV6 loopback address.
If I ping 127.0.0.1, I receive a reply from 127.0.0.1 as expected.
Why is there a difference when hostname resolution of localhost is indeed 127.0.0.1?

Technically there is nothing wrong with pinging either
localhost
or127.0.0.1
since they will normally (there are exceptions if the user points localhost to some other server but that's quite unusual) point to the same server (your local computer). – Hengjie – 2013-02-10T09:04:37.393
