[-- Attachment #1 --] There's risk to our IPv6 folks if we MFC this. This file is the old one still (and it took them 6 weeks to get the last one updated past its expiration date). The IERS one is up to date, expires Jun 2025. The IANA has a december expiration date finally, though we leared 3 weeks ago there's no leap in December, so that's why the IERS one was updated. So this is better than nothing, but we're setting ourselves up for a problem this December / January.... The last time this issue came up, I was kinda opposed to FreeBSD running this since IERS did. However, I either didn't know at the time, or didn't appreciate at the time the lack of IPv6 for this data source would be a problem. Since we have no other reliable source, maybe we need to stand up a FreeBSD mirror after all. So this is better than nothing, but we may need to do more.
