Our networking team is in the habit of entering the IP address of every network interface on a router under one name. The very first address entry is their out-of-band management interface. "rrset-order fixed" is used on their domain for address records, so they can ssh to the router by name reliably and not have to worry about interfaces that are down or that filter SSH. We also have cases where redundancy is being configured but is not yet complete. In that case only the first IP is active. If we don't use "rrset-order fixed" we get complaints that connections take too long and there must be a network error.

EXTERNAL Hey, BIND 9 supports a fixed rrset ordering (that is keeping the order of the RRSets from the zone file). It has to be configured at the compile time, it takes more memory (to record that order) and it's a #ifdef all over the places. So, henceforth, my question - does anyone still uses that? And if yes, what are the use cases? I think BIND is the only server that actually supports this, so it doesn't feel like the DNS can't function without it.
