Map of regional Internet registries The regional Internet registry system evolved, eventually dividing the responsibility for management to a registry for each of five regions of the world. The regional Internet registries are informally liaised through the unincorporated Number Resource Organization (NRO), which is a coordinating body to act ...
By using split-horizon DNS the same name can lead to either the private IP address or the public one, depending on which client sends the query. This allows for critical local client machines to access a server directly through the local network, without the need to pass through a router.
The contents of the root zone file is a list of names and numeric IP addresses of the root domain authoritative DNS servers for all top-level domains (TLDs) such as com, org, edu, and the country code top-level domains (it also includes that info for root domain, the dot). On 12 December 2004, 773 different authoritative servers for the TLDs ...
The root servers clusters have the official names a.root-servers.net to m.root-servers.net. [6] To resolve these names into addresses, a DNS resolver must first find an authoritative server for the net zone. To avoid this circular dependency, the address of at least one root server must be known for bootstrapping access to the DNS. For this ...
Network address mapping. Most network address translators map multiple private hosts to one publicly exposed IP address. Here is a typical configuration: A local network uses one of the designated private IP address subnets (RFC 1918 [5]). The network has a router having both a private and a public address.

The Common Address Redundancy Protocol or CARP is a computer networking protocol which allows multiple hosts on the same local area network to share a set of IP addresses. Its primary purpose is to provide failover redundancy, especially when used with firewalls and routers. In some configurations, CARP can also provide load balancing ...
