Is this an ipv6-address? If so, why 3 ::: and slash

Ohh that's so cool. That makes sense. But is that an official notation or just what the app spits out in his own style?

As far as I recall the official notion is with square brackets, to avoid exactly this confusion.
But nobody uses it, to be honest

It's only official for URIs, outside of URIs there is no official notation because there is no official notation for ports. :port is also a URI thing so while you'll find a lot of software using URI syntax or something similar it's the wild west when URIs aren't in use

Can it actually be ambiguous though? If not, we should adopt this standard instead. It's so annoying adding the square bracket

The square bracket is the standard, eg. as the IP-literal from RFC3986 <https://datatracker.ietf.org/doc/html/rfc3986#section-3.2.2>.
Any case where the three colons occur happens because someone just takes the IP address, prints a colon after it and the port, rather than just using existing libraries that do this right.

Sure but is it actually ambiguous is what I wonder
Scoopta@programming.dev · 1 pts · 333d
It is ambiguous. See this which could be either an address or address + port. 2001:db8:1::2:443
That is a valid address...expanded it would be 2001:db8:1:0:0:0:2:443 ...but oh no, the intent was for it to be 2001:db8:1:0:0:0:0:2 with port 443...but you'd never know
dysprosium@lemmy.dbzer0.com · 1 pts · 333d
Yes good example. So it's down to a game of "do I know all my ports." 443, 22, 80, 5900, 8080, etc

Hmmm, this is weird. I was trying to figure out the / at the start since no one answered that. I know java's network stack does that but it doesn't format addresses like this example. Java formats individual addresses like
/2001:db8:0:0:0:0:0:0or if a port is included/[2001:db8:0:0:0:0:0:0]:443so it's like...kinda a java format? Not suredysprosium@lemmy.dbzer0.com · 1 pts · 331d
Just Mihon then probably
