what is the meaning of nat in networking
Network address translation
title: Network address translation text: is a private LAN, the main phone number is the public IP address, and the individual extensions are unique port numbers. With NAT, all communications sent to external hosts actually contain the "external" IP address and port information of the NAT device instead of internal host IP addresses or port numbers. NAT only translates IP addresses and ports of its internal hosts, hiding the true endpoint of an internal host on a private network. NAT operation is typically transparent to both the internal and external hosts. Typically the internal host is aware of the true IP address and TCP or title: Natter Social Network text: Natter Social Network Natter was a social network, often referred to as a "microblogging" or even "micro-microblogging" platform. Natter allowed its users or “natterers” to post up to 100 characters and an image in each post, which could then be seen by any online users. Natter was first launched in 2014 as a website at natter.com but has since launched apps for both iOS and Android. The user base has grown and describes themselves as the natter community. Originally, each post could only contain up to three words. On Friday, July 29, 2016, Natter ceased operations, due to competition, as title: NAT traversal text: NAT traversal Network address translator traversal is a computer networking technique of establishing and maintaining Internet protocol connections across gateways that implement network address translation (NAT). NAT traversal techniques are required for many network applications, such as peer-to-peer file sharing and Voice over IP. NAT devices allow the use of private IP addresses on private networks behind routers with a single public IP address facing the Internet. The internal network devices communicate with hosts on the external network by changing the source address of outgoing requests to that of the NAT device and relaying replies back to the originating device. title: Non-access stratum text: Non-access stratum Non-access stratum (NAS) is a functional layer in the UMTS and LTE wireless telecom protocol stacks between the core network and user equipment. This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves. The NAS is defined in contrast to the Access Stratum which is responsible for carrying information over the wireless portion of the network. A further description of NAS is that it is a protocol for messages passed between the User Equipment, also known as mobiles, and Core Nodes (e.g. Mobile Switching Center, title: Network address translation text: Network address translation Network address translation (NAT) is a method of remapping one 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. The technique was originally used as a shortcut to avoid the need to readdress every host when a network was moved. It has become a popular and essential tool in conserving global address space in the face of IPv4 address exhaustion. One Internet-routable IP address of a NAT gateway can be used for an entire private network. IP masquerading is a
