Why are these results different than normal?

[RYFA 1]

Not the best title but I'll explain..

So on some servers in the IPLeak.net DNS test there are two servers detected instead of one like normal one is the IPV4 address the other the IPV6 both for the server I'm connected to like this..



This only happens on some servers not all so I assume this is either a bug on the website or something is different about some of the servers. Did they change something?

This second screenshot is what tests normally look like..


As shown in the second screenshot normally tests only show one server detected.

Why are some servers different now?

The first screenshot is from the server Hyadum and the second is from the server Alterf.

Also I'm using firefox as my browser if that matters at all.

Thanks for your help.

Sometimes IPv4 answers quicker, sometimes IPv6. Sometimes only one of them. Since both addresses are the servers themselves, there is nothing to worry about.
