Users were able to create a sub-domain under a few domains owned by No-IP. In May 2000, Vitalwerks Internet Solutions, LLC was formed as the parent company of No-IP. In January 2001 No-IP began offering paid managed DNS services which allowed users to set up dynamic DNS using their own domain name. Later that year, they began to offer email ...
According to RFC 1034, "a domain is a subdomain of another domain if it is contained within that domain". Based on that definition, a host cannot be a subdomain, only a domain can be a subdomain. A subdomain will also have a separate zone file with a SOA record (Start of Authority). Most domain registries only allocate a two-level domain name ...

The format of a zone file is defined in RFC 1035 (section 5) and RFC 1034 (section 3.6.1). This format was originally used by the Berkeley Internet Name Domain (BIND) software package, but has been widely adopted by other DNS server software – though some of them (e.g. NSD, PowerDNS) are using the zone files only as a starting point to compile them into database format, see also Microsoft ...
The Public Suffix List (PSL) is a community-maintained list of rules that describe the internet domain name suffixes under which independent organisations can register their own sites.

The Domain Name System (DNS) servers, sometimes likened to a telephone directory, translate browser requests for domain names into the IP address assigned to that computer or network. The original bill requires these servers to stop referring requests for infringing domains to their assigned IP addresses.
DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction.It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers.
