Ping localhost returns IPV6

[techie08]

Is there a reason why when i ping the localhost server (in this case my new 2012DCs) it returns the IPv6 address of ::1? IPv6 is disabled so i'm just curious to know why?

 

Thanks

It's because you have IPv6 enabled - With any address if you add -4 to the end it will return the IPv4 address:

 

ping localhost -4

In the network adapter, IPV6 is unchecked. Does that mean its on somewhere else?

Unchecking it does not disable IPv6, you need to look at this link:

On 2008 R2 there was also a registry entry to disable IPv6

I wouldn't disable it, I would fix your network stuff first.

 

::1 is the loopback address (the IPV6 version of 127.0.0.1) so something is a miss.

Yup - also check the link I put up.

I wouldn't disable it either, I always leave it enabled. It's amazing the amount of servers I come across and it's unticked, thinking it disables it.
