denoting IPv6 addresses and ports

[William F. Maton]

Greetings

	I read RFC 2732 on denoting IPv6 addresses for URL's, but I have a
question for the general case.  Is there a standard method for writing
down, on a piece of papaer, or a document or some other such thing the
format of an IPv6 address and a port number?  For example, I want to write
down the shorthand for, "IPv6 address 3ffe:456:45e::34, port number 23."
Do I write it like the examples in the RFC such that this:

      http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:80/index.html
      http://[1080:0:0:0:8:800:200C:417A]/index.html

expresses an IPv6 literal for a URL, while writting this:

	 [3ffe:456:45e::34]:23

would be clear to someone as meaning the telnet port at address 
3ffe:456:45e::34?

I'm not necessarily talking about how API's would interpret this, but how
a human would interpret this on a napkin, for example.

In short, what's the general case of RFC 2732?

Sorry if this is a FAQ, couldn't find anything concrete while scanning
through the archives.

TIA,
