+## Reverse DNS lookups for internal IPs
 
-By default Warp will send reverse DNS querys (IP to hostname) to public DNS servers, in order to resolve internal reverse DNS lookups a local domain fallback entry needs to be added for in-addr.arpa that points to your internal DNS server IP. in-addr.arpa is the "domain" used for reverse DNS queries, so adding a local domain fallback entry for this will send reverse DNS queries to your local DNS server.
+By default, Warp sends [reverse DNS queries](https://www.cloudflare.com/learning/dns/glossary/reverse-dns/) to public DNS servers. To lookup the domain name associated with an internal IP address, [add a local domain fallback entry](#add-a-domain) for `in-addr.arpa` (IPv4) and/or `ip6.arpa` (IPv6) that points to your internal DNS server IP. `in-addr.arpa` and `ip6.arpa` are top-level domains [reserved](https://www.iana.org/domains/arpa) for reverse DNS queries. By adding a local domain fallback entry for these domains, all reverse DNS queries (such as `dig -x 1.1.1.1`) will now resolve through your local DNS server.
