# Hostname PTR Record naming docs

This is a updated version (2025) hostname conventions design Reason to update:

Try to limit the length of FQDN so it can be trimed when needed.

Try to ignore vendor when possible, so we consider all servers are one.

Try to include vendor to locations, when needed.

Try to use a standard domain, for example srv.DOMAIN.ltd or simplify just DOMAIN.ltd for all hostname.
