Why has ping started to resolve hostnames to IPv6 addresses?

5

Why would my computer (Vista Business) begin to start pinging using IPv6? I have not to my knowledge made any change to enable this.

When I ping a local computer with it's hostname, ping has started to display the IP6 address it resolves to and not the IPv4 address.

Any ideas?

you can force IPv4 by using ping -4 hostname – ndreisg – 2020-02-20T08:53:43.750

Because computer can understand only numbers and not name like ( 0 and 1).And also when you work on domain there is a Reverse Look-up zone which has done this function. – None – 2011-08-16T09:31:50.623

It's probably because when ping looks up the hostname your DNS returns an ip6 address. Check with whomever is in charge of your DNS server.

Just go to network card properties, uncheck the IPV6 address option and restart the machine. default ping to hostname will resolve to ipv4 address.

2Not an answer to the question which is just "why". Also you will want IPv6 support when possible. – MarioDS – 2014-07-31T21:19:58.983
