Reverse DNS Lookup
Reverse DNS lookup is the resolution of an IP address to its designated domain name. Enable to allow reverse DNS lookup.
* If there are multiple hosts resolving to same IP Address then Reverse DNS Lookup can be configured only for one of the IP Address.
Only A, AAAA, and PTR type of DNS records are supported.
Address (A) record - points a hostname to an IP address and returns a 32-bit IPv4 address.
AAAA record - points a hostname to an IP address and returns a 128-bit IPv6 address.
Pointer records (PTR) - are just the reverse of A records and are used for reverse lookups. It maps IP address to a hostname.
Maximum DNS entries supported - 1024
If the device interface is used as a DNS in the Client system then a query is sent to the configured DNS servers prior to querying the ROOT severs.
