For IPv6, the range calculator defaults to assuming that a /64 range is allocated to each user. Therefore, by default, it stops once it reaches /64 without looking for more precise ranges. There are two ways to request more results:
nslookup operates in interactive or non-interactive mode. When used interactively by invoking it without arguments or when the first argument is - (minus sign) and the second argument is a hostname or Internet address of a name server, the user issues parameter configurations or requests when presented with the nslookup prompt (>).
The IP address of a public server is also important, similar in global uniqueness to a postal address or telephone number. Both IP address and port number must be correctly known by all hosts wishing to successfully communicate. Private IP addresses as described in RFC 1918 are usable only on private networks not directly connected to the internet.
For example, to do a reverse lookup of the IP address 8.8.4.4 the PTR record for the domain name 4.4.8.8.in-addr.arpa would be looked up, and found to point to dns.google. If the A record for dns.google in turn pointed back to 8.8.4.4 then it would be said to be forward-confirmed.
The biggest delay in getting RDAP done turned out to be the bootstrap, figuring out where the server is for each top-level domain, IP range, or ASN range. IANA agreed to host the bootstrap information in suitable registries, and publish it at a well-known location URLs in JSON format. Those registries started empty and will be gradually ...

The function getnameinfo() converts the internal binary representation of an IP address in the form of a pointer to a struct sockaddr into text strings consisting of the hostname or, if the address cannot be resolved into a name, a textual IP address representation, as well as the service port name or number. The function prototype is specified ...
Anycast rendezvous point can be used in Multicast Source Discovery Protocol (MSDP) and its advantageous application as Anycast RP is an intra-domain feature that provides redundancy and load-sharing capabilities. If the multiple anycast rendezvous point is used, IP routing automatically will select the topologically closest rendezvous point for ...
