Hi DNSOP,
The practice of DNS Load Balancing -- sending different answers to
different resolvers to optimize latency and avoid overload -- has been
around for at least 25 years, and remains as popular as ever. It's
never really been supported in the DNS standards though, and it
particularly conflicts with the concepts of zone files, zone transfers,
and offline signing.
I think it's time we did better on this front. To that end, Shane Kerr
and I will be hosting a side meeting at IETF 120 on DNS Load Balancing,
tentatively scheduled for Wednesday afternoon:
https://wiki.ietf.org/en/meeting/120/sidemeetings#wednesday-24-july
<https://wiki.ietf.org/en/meeting/120/sidemeetings#wednesday-24-july>
We hope to develop a strategy for standardization, discuss topics that
should be in or out of scope, and possibly present a demo of what
standards support for load balancing could look like. Please join us
(in-person or remotely) if you have an interest in this topic.
For discussion in the next few weeks before the meeting, we'll be
experimenting with the IETF's new Slack channels for collaboration. If
you have thoughts or questions, please join our channel (using your
Datatracker account):
Can you please ensure that there's time on the agenda for discussion on
why it remains a bad idea to use the internet's name to resource mapping
scheme to perform what should be achieved in the routing layer?
The DNS was never designed intended to deliver different answers to
different users. DNSSEC solidified that and the practise IMNSHO should
be discouraged, not standardised.
