At the 53rd IETF in Minneapolis, the network will be running with dynamic
updated reverse DNS.
If configured on your laptop and at your home name server, this will
enable you to get a dynamically allocated address which has your own
domain name both in the forward zone and in the reverse zone.
IETF participants that wish to take advantage of this feature may find
detailed instructions at the following URL:

Questions regarding setup can be sent to
