Dns ipv4.domain.tld

Hi there,

What does the ipv4.domain.tld why is it there?

With kind regards.

What do you mean? Could you please clarify a little bit this issue?

Sorry,

I know what i meen.

In the DNS Settings i see ipv4.domain.tld A <ip-adress> what does this do?

Is it the same record as domain.tld A <ip-adress>.

Does anybody know?

It's for when you have a dual stack - ipv4 and ipv6.

www. will have both ipv4 and ipv6 addresses

ipv4. only a ipv4 address

ipv6. will only have a ipv6 address

I'm not sure why you would need it in an ipv4 only environment, maybe there's an RFC for it now.

So just for just for the check?

ipv4.domain.tld A <ip-adress>
Has the same purpuse as:
domain.tld A <ip-adress>
just for the ipv4 or if you use
ipv6.domain.tld A <ip-adress>

its for the ipv6

 

[Lloyd_mcse]

Yeah, that's correct...

domain.tld A <ipv4-address>
domain.tld AAAA <ipv6-address>

ipv4.domain.tld A <ipv4-address>
ipv6.domain.tld AAAA <ipv6-address>

to be exact.
