Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, [1] for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space.
Network configuration and change management (NCCM) is a discipline in information technology. Organizations utilize NCCM as a way to: automate changes;
Microsoft Configuration Manager (ConfigMgr) is a systems management software product developed by Microsoft for managing large groups of computers providing remote control, patch management, software distribution, operating system deployment, and hardware and software inventory management.
Configuration Management (CM) is an ITIL-specific ITSM process that tracks all of the individual CIs in an IT system which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process.
NAT traversal with SBC during user registration. Similar to the registration case, the SBC will also include itself in the path of INVITE and other request messages. When receiving an INVITE from a user agent behind a NAT, the SBC will include a via header with its own address, replace the information in the contact header with its own address and also replace the address information in the ...
NAT Port Mapping Protocol (NAT-PMP) is a network protocol for establishing network address translation (NAT) settings and port forwarding configurations automatically without user effort. [1] The protocol automatically determines the external IPv4 address of a NAT gateway, and provides means for an application to communicate the parameters for ...
