Last night after the IETF plenary session I happened to be part of a small gathering of geeks who among other things were speaking of how IPv6 will eventually supplant IPv4, so I spontaneously (well, after some coaxing) came up with the following limerick:
There once was a man named Al Gore,
Who thought that the phone could do more;
He invented the Net,
But we'll do better yet,
For he only developed 'v4.
To the universal deployment of IPv6!
