What is a domain name and why is it so important for your online presencethis article provides details on domain names, where you can register and how to correctly choose one for your company.
Domains usually need at least two authoritative name servers that perform name resolution for the domain. Domain names are often referred to simply as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the name, only an exclusive right of use. Domain names are often seen in analogy to real estate in that (1) domain names are foundations on which a website (like a house or commercial building) can be built and (2) the highest “quality” domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, search engine optimization, and many other criteria. Domain registrations were free of charge when the DNS was new. Domain name sales occurring in the aftermarket are frequently submitted to the DN journal. Domain names are hostnames that allow us to remember websites more easily than using an IP address. Domain names are allowed to have letters, digits, and hyphens. Domain names are also not case sensitive Examples. Domain names, and their corresponding IP addresses, must be unique. Domain name servers are computers that translate domain names to IP addresses. Domain name registration prices are typically anywhere from $15. Domain names are looked up on name servers in the DNS hierarchy to resolve them to numerical IP addresses. Domain names allow Internet users to type in a name, such as mybrand. DomainName Servers are connected to the internet and use special software totranslate domain names into the numerical addresses (Internet Protocolnumbers) used by the Internet. Domain names were developed to make it easy for people to find things on the Internet. Domain names are used in URLs to identify particular Web pages. Domain name registration, Web hosting, e-mail services, domain search, and SEO services. Domain names consist of a series of words separated by dots and can contain only alphabet, numbers and the hyphen. – The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource participating in the Internet. It associates various information with domain names assigned to such participants. Most importantly, it translates human meaningful domain names to the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices world-wide. An often used analogy to explain the Domain Name System is that it serves as the “phone book” for the Internet by translating human-friendly computer hostnames into IP addresses. The Domain Name System makes it possible to assign domain names to groups of Internet users in a meaningful way, independent of each user’s physical location. Internet domain names are easier to remember than IP addresses such as 208. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are assigned to be responsible for their particular domains, and in turn can assign other authoritative name servers for their sub-domains. In general, the Domain Name System also stores other types of information, such as the list of mail servers that accept email for a given Internet domain. By providing a world-wide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet. The Domain Name System also defines the technical underpinnings of the functionality of this database service. At the request of Jon Postel, Paul Mockapetris invented the Domain Name system in 1983 and wrote the first implementation. [edit] The domain name spaceDomain names, arranged in a tree, cut into zones, each served by a nameserver. The domain name space consists of a tree of domain names. Each node or leaf in the tree has zero or more resource records, which hold information associated with the domain name. Authority is said to be delegated for a portion of the old space, usually in form of sub-domains, to another nameserver and administrative entity. A domain name usually consists of two or more parts (technically a label), which is conventionally written separated by dots, such as example. The rightmost label conveys the top-level domain (for example, the address www. Each label to the left specifies a subdivision, or subdomain of the domain above it. Note: subdomain expresses relative dependence, not absolute dependence. The whole domain name may not exceed a total length of 253 octets. [5] In practice, some domain registries may have shorter limits. A hostname refers to a domain name that has one or more associated IP addresses; ie: the ‘www. The Domain Name System is maintained by a distributed database system, which uses the client-server model. Each domain or subdomain has one or more authoritative DNS servers that publish information about that domain and the name servers of any domains subordinate to it. The top of the hierarchy is served by the root nameservers: the servers to query when looking up (resolving) a top-level domain name (TLD). , translation of a domain name into an IP address. Since this can introduce a circular dependency if the nameserver referred to is under the domain that it is authoritative of, it is occasionally necessary for the nameserver providing the delegation to also provide the IP address of the next nameserver. For example, assume that the sub-domain en. DNS also supports wildcard DNS records that will match requests for non-existent domain names. A wildcard DNS record is specified by using a “*” as the left most label (part) of a domain name, e. When an application (such as a web browser) tries to find the IP address of a domain name, it doesn’t necessarily follow all of the steps outlined in the Theory section above. Specifically, it implies that [1] when you make a DNS change, it somehow spreads to all other DNS servers (instead, other DNS servers check in with yours as needed), and [2] that you do not have control over the amount of time the record is cached (you control the TTL values for all DNS records in your domain, except your NS records and any authoritative DNS servers that use your domain name). When one changes the NS records for one’s domain or the IP addresses for hostnames of authoritative DNS servers using one’s domain (if any), there can be a lengthy period of time before all DNS servers use the new information. And any DNS changes on your domain other than the NS records and authoritative DNS server names can be nearly instantaneous, if you choose for them to be (by lowering the TTL once or twice ahead of time, and waiting until the old TTL expires before making the change). A number of large ISPs have configured their DNS servers to violate rules (presumably to allow them to run on less-expensive hardware than a fully-compliant resolver), such as by disobeying TTLs, or by indicating that a domain name does not exist just because one of its name servers does not respond.
In the business of marketing domain names, “premium” domain names are often valuable, and have particular characteristics. The business of resale of previously registered domain names is known as the “domain aftermarket”. Certain domains, especially those related to business, gambling, pornography, and other commercially lucrative fields of digital world trade have become very much in demand to corporations and entrepreneurs due to their importance in attracting clients. There are disputes about the high values of domain names claimed and the actual cash prices of many sales such as Business. To date, and according to Guinness World Records and MSNBC, the most expensive domain name sales on record as of 2004 were[3]:Business.

DNS servers are not required to support recursive queries. DNS primarily uses UDP on port 53 [8] to serve requests. DNSSEC, however, works on complete RR sets in a canonical order. DNS was not originally designed with security in mind, and thus has a number of security issues. – This mechanism has made the DNS distributed, fault tolerant, and helped avoid the need for a single central register to be continually consulted and updated. Other identifiers such as RFID tags, UPC codes, International characters in email addresses and host names, and a variety of other identifiers could all potentially utilize DNS [1]. For this purpose it defines the DNS protocol, a detailed specification of the data structures and communication exchanges used in DNS, as part of the Internet Protocol Suite (TCP/IP). The context of the DNS within the Internet protocols may be seen in the following diagram. The DNS protocol was developed and defined in the early 1980s and published by the Internet Engineering Task Force (cf. The DNS was invented in 1983, shortly after TCP/IP was deployed. Several more-recent RFCs have proposed various extensions to the core DNS protocols. BIND was widely distributed, especially on Unix systems, and is the dominant DNS software in use on the Internet. A DNS zone consists of a collection of connected nodes authoritatively served by an authoritative nameserver. The client-side of the DNS is called a DNS resolver.
