Can you enable IPv6 on *.au.pool.ntp.org please?

1

I’m in the process of creating a bunch of geographically redundant IPv6 Stratum 1 NTP servers and I’m hoping we can flick the switch on enabling AAAA record on all the AU pools (au.pool along with 0, 1, and 3).

This will tie into a further chicken-and-egg talk about IPv6 at Linux.conf.au in January, and I’m aiming to have at least 6 100mbit+ Stratum 1 NTP servers in datacenters around AU by then.

Unfortunately, because most people are lazy and just put ‘au.pool.ntp.org’ into their NTP servers, they don’t get AAAA records, so they don’t get IPv6 and it’s a vicious circle of me not being able to show usage, which means people aren’t using it.

This is supposedly being worked on. See this thread: Intention to enable IPv6 by default in 2017 and this one: It's 2019 and still no IPv6 by default?

The code has been written, it’s just not been merged

Hello @ask! When you do this, can you please do it for NL as well (or perhaps even better: do it for the entire pool at once).

Many thanks!

It appears that this will never happen - my pull request was closed without comment, and … I guess that’s it!

Use this and IPv6 will be served:

bas@workstation:~$ nslookup 2.pool.ntp.org 1.1.1.1
Server:		1.1.1.1
Address:	1.1.1.1#53

Do not use regional pools, as the pool will autoselect the best servers.

Which, in most cases, will mean the pool will automatically limit you to servers from the country zone that the system believes you are located in.

Exceptions apply if you use privacy-minded DNS resolvers such Cloudflare or Quad9, in which case you will get servers from the country zone the system believes the particular DNS server instance responding to a particular query is located in. Which in most cases likely are servers from your own country zone again, but may occasionally be beyond that.
