In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. [1] The process of reverse resolving of an IP address uses PTR ...
This example Prefix WhoIs query shows various information about an IP address including its network origin and registrar details. Prefix WhoIs is an open source project that develops and operates a free whois-compatible framework for stockpiling and querying various routing and registry information.
Starting 1991-06-01, was used to map Public Data Network addresses to IP addresses. Returned to IANA 2008-01-22. This network was reclaimed by IANA in 2007 and was subsequently re-allocated in 2010. See RFC 877 and RFC 1356 for historical information. [10] 15.0.0.0/8 ARIN: 1991-09 Various registries (maintained by ARIN).
Usually referred to as ANY (e.g., in dig, Windows nslookup, and Wireshark). In 2019, RFC8482 [14] standards-track publication led many DNS providers, including Cloudflare, [15] to provide only minimal responses to "ANY" queries, instead of enumerating records.

The IP address of the destination is used to make decisions about routing IP packets to other networks. IPv6 is the successor to the first addressing infrastructure of the Internet, Internet Protocol version 4 (IPv4). In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 addresses have a size of 128 bits.

Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
Lookups of IP address allocations are often limited to the larger Classless Inter-Domain Routing (CIDR) blocks (e.g., /24, /22, /16), because usually only the regional Internet registries (RIRs) and domain registrars run RWhois or WHOIS servers, although RWhois is intended to be run by even smaller local Internet registries, to provide more ...
