DNS Hosting Service
A DNS hosting service is a service that runs Domain Name System (DNS) servers. Most, but not all, domain name registrars include DNS hosting service with registration. Free DNS hosting services also exist. Many third-party DNS hosting services provide dynamic DNS. DNS hosting service is optimal when the provider has multiple servers in various geographic locations that provide resilience and minimize latency for clients around the world. By operating DNS nodes closer to end users, DNS queries travel a much shorter distance, resulting in faster Web address resolution speed. DNS can also be self-hosted by running on generic Internet hosting services. Free DNS A number of sites offer free DNS hosting, either for second-level domains registered with registrars which do not offer free (or sufficiently flexible) DNS service, or as third-level domains (selection.somedomain.com). These services generally also offer Dynamic DNS. Free DNS typically includes facilities to manage A, MX ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domain Name System
The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information with ''domain names'' (identification (information), identification String (computer science), strings) assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over subdomains of their allocated name space to other name servers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domain Name Registrar
A domain name registrar is a company, person, or office that manages the reservation of Internet domain names. A domain name registrar must be accredited by a generic top-level domain (gTLD) Domain name registry, registry or a country code top-level domain (ccTLD) registry. A registrar operates in accordance with the guidelines of the designated domain name registry, domain name registries. As of March 2024, there are 2,800 domain name registrars accredited by ICANN. History Creation The need for a central authority to assign or administer domain names emerged from collaboration among computer network pioneers as they created the Domain Name System in the 1980s. In a 1982 draft Request for Comments (RFC), editor Jonathan Postel proposed a "czar of domains." In her revisions of the draft, Jake Feinler crossed out "czar" and introduced the term "registrar." She designated the InterNIC, DOD Network Information Center, of which she was the head, as the registrar of top-level domai ...

Dynamic DNS
Dynamic DNS (DDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information. The term is used to describe two different concepts. The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. These mechanisms use TSIG to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the standard for updating DNS records. These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently. Background In the initial stages of the Internet (ARPANET), addressing of hosts on the network was achieved by static translation tables that mapped hostnames to IP addresses. The tables were maintained manually in form of the host file. The Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Hosting Service
An Internet hosting service is a service that runs servers connected to the Internet, allowing organizations and individuals to serve content or host services connected to the Internet. A common kind of hosting is web hosting. Most hosting providers offer a combination of services e-mail hosting, website hosting, and database hosting, for example. DNS hosting service, another type of service usually provided by hosting providers, is often bundled with domain name registration. Dedicated server hosts, provide a server, usually housed in a datacenter and connected to the Internet where clients can run anything they want (including web servers and other servers). The hosting provider ensures that the servers have Internet connections with good upstream bandwidth and reliable power sources. Another popular kind of hosting service is shared hosting. This is a type of web hosting service, where the hosting provider provisions hosting services for multiple clients on one physical ...

Fast-flux DNS
Fast flux is a domain name system (DNS) based Evasion (network security), evasion technique used by cyber criminals to hide phishing and malware delivery websites behind an ever-changing network of compromised hosts acting as Reverse proxy, reverse proxies to the backend Botnet#Client–server model, botnet master—a bullet proof hosting, bulletproof Autonomous system (Internet), autonomous system. It can also refer to the combination of peer-to-peer networking, distributed command and control (malware), command and control, web-based Load balancing (computing), load balancing and Proxy server, proxy redirection used to make malware networks more resistant to discovery and counter-measures. The fundamental idea behind fast-flux is to have numerous IP addresses associated with a single fully qualified domain name, where the IP addresses are swapped in and out with extremely high frequency, through changing Domain Name System#Resource records, DNS resource records, thus the Name ...

Remote Backup Service
A remote, online, or managed backup service, sometimes marketed as cloud backup or backup-as-a-service, is a service that provides users with a system for the backup, storage, and recovery of computer files. Online backup providers are companies that provide this type of service to end users (or clients). Such backup services are considered a form of cloud computing. Online backup systems are typically built for a client software program that runs on a given schedule. Some systems run once a day, usually at night while computers aren't in use. Other newer cloud backup services run continuously to capture changes to user systems nearly in real-time. The online backup system typically collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers or off-site hardware. There are many products on the market – all offering different feature sets, service levels, and types of encryption. Providers of this type of service frequently target ...

List Of DNS Record Types
This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information ... (DNS). It also contains pseudo-RRs. Resource records Other types and pseudo-RRs Other types of records simply provide some types of information (for example, an HINFO record gives a description of the type of computer/OS a host uses), or others return data used in experimental features. The "type" field is also used in the protocol for various operations. Obsolete record types Progress has rendered some of the originally defined record-types obsolete. Of the records listed at IANA, some have limited use, for various reasons. Some are marked obsolete in the list, some are for very obscure services, some ar ...
