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.
