The history of domain names 87:The terms "domain" or "domain name" are used in many contexts beyond the 88:DNS described here. Very often, the term domain name is used to refer 288: of the domain name space tree names a set of information, and 293: uses some of its domain names to identify hosts; queries for 357:The domain name space is a tree structure. Each node and leaf on the 367:The domain name of a node is the list of the labels on the path from the 369:domain name are printed or read left to right, from the most specific 373:Internally, programs that manipulate domain names should represent them 375:an octet string. Because all domain names end at the root, which has a 377:byte of zero to terminate a domain name. 379:By convention, domain names can be stored with arbitrary case, but 380:domain name comparisons for all present domain functions are done in a 384:refer to either using "a" or "A". When you receive a domain name or 394:that we may someday need to add full binary domain names for new 397:When a user needs to type a domain name, the length of each label is 399:domain name ends with the root label, this leads to a printed form which 402: - a character string which represents a complete domain name 406: domain name which is incomplete, and should be completed by 415:relative to a single origin domain name. The most common interpretation 421:domain name (i.e., the sum of all label octets and label lengths) is 424:A domain is identified by a domain name, and consists of that part of 425:the domain name space that is at or below the domain name which 486:which is a subset of the usual text representation for domain names, 492:address @ is mapped into a domain name by 494:contains), converting into a domain name using the usual 495:text format for domain names (dots denote label breaks), and 496:concatenating the two to form a single domain name. Thus the mailbox 505:HOSTMASTER@SRI-NIC.ARPA is represented as a domain name by 520:The following figure shows a part of the current domain name space, and 547:EDU, and ARPA.

The address RRs use a standard IP address 760:This example shows six RRs, with two RRs at each of three domain names. 801:domain name, it checks to see if the resource set consists of a CNAME 803:record in the response and restarts the query at the domain name 881:A standard query specifies a target domain name (QNAME), query type 913:Using the query domain name, QTYPE, and QCLASS, the name server looks 919:that returns a domain name in a relevant RR may also return the RR that 920:binds that domain name to an address. 958:resource to a domain name or domain names that have that resource. For 959:example, while a standard query might map a domain name to a SOA RR, the 968:inverse queries because the domain system is organized by domain name 1054:name space so that each domain name was in a separate zone or so that 1389:the form "*.", where is any domain name. 1438:This would cause any MX query for any domain name ending in X.COM to 1587:Resolvers are programs that interface user programs to domain name 1644: domain name "4.3.2.1.IN-ADDR.ARPA". 1801:SNAME the domain name we are searching for. 1889:starting at SNAME, then the parent domain name of SNAME, the 2153:Relative and absolute domain names may be freely intermixed in a master 2598:RRs for the domain name ISI.EDU. }}}
