I’m told the address is invalid when I try to use a IPv6 literal address for my web monitor. I want to use a literal address as all my websites’ domains are dual-stack with IPv4 and IPv6, and I want to monitor IPv4 and IPv6 services separately.

Here is an example of an IPv6 literal address as supported in all browsers and as standardized in RFC 2732:
http:// [2001:db8::dead:e1f]/

Please address this issue as the world has already run out of IPv4 addresses and the whole industry need to get this stuff working yesterday.

PS: I’m not impressed that this forum software can’t recognize an IPv6 address as an URL either. This works in competing products such as UptimeRobot.
