I think the Telecom Digest is one of Pat's biggest and longest-running accomplishments. The biggest compliment for this that I know can be found at http://1997.webhistory.org/www.lists/www-talk.1993q1/0241.html Tim Berners-Lee forwarding a suggestion to make the telecom digest available on the web in order to *promote the web*.

This .signature hit a bit of a raw nerve today. I thought I was ready
to support IPv6 years ago. Then along came "privacy" addresses and
threw all of that right out the window. I don't want to repeat my
rant here, so please see my blog post about why IPv6 as currently
specified and implemented is unsuitable for use on anything but small
or very tightly controlled networks:
Everything I write about could be fixed -- indeed, could have been
prevented -- but the software vendors who decided that turning on
"privacy" addresses would make it seem as if they were doing a good
thing should have talked with the network hardware vendors (who would
have told them that this was insane). We'll probably end up using
DHCPv6 (and turning on DHCP snooping to block clients that don't
use a DHCP-assigned IPv6 address) but we don't yet have the ability to
A reasonable alternative to "privacy" addresses -- depending on the
threat model -- would be either Cryptographically Generated Addresses
or generating the interface ID as a 62-bit truncated hash of (prefix,
MAC-48) rather than a random number, so that it would at least be
stable and traceable within the domain of a single network operator.
