This is how embedded stacks (LWiP) store IPv4. Didnt' know browsers could respond to it thought.

Mixing IPv4 and IPv6 is just evil.

It’s how any reasonable software represents IPv4 addresses. Dotted decimal is only for human convenience (and honestly, I’d argue that 0xDEADBEEF would be just as convenient, after all people turned out to handle HTML/CSS hex colors just fine!)
