TTL for PTR records on Windows 2003 Server DNS
- by Kyle Brandt
When I look at the TTL (Time to Live) for PTR records (Reverse Lookup Zone) on one of our Windows 2003 DNS servers I see some are at 15 minutes, others are at 20. They have "Delete this record when it becomes stale" checked.
These PTR records are for workstations that get IPs from Windows DHCP, so I think that creates the PTR records dynamically?
How is TTL for these records set?
