SRV records etc

Misspoke, and not critical to the original thread, but for completeness.

Taking a second look dynamic DNS does not use HINFO records for the machine fingerprint, it uses TXT records.

I can't find anything that says it (HINFO) has been officially deprecated, nor do I find anything that says it's really used by anyone anymore.

HINFO records seem to be used by dynamic DNS to store fingerprints for machines, so if a specific machine's information changes, the dhcp server will be able to recognize and delete stale records.

To the original point, we have some SVC records here, they seem to work well and have not given trouble other than # nslint not knowing what they are.

Does anyone know of a new/update nslint?

I thought they were deprecated ages ago, but I can't find anything official about that.
