What is NAT IP means?
network address translation
NAT stands for network address translation. It’s a way to map multiple local private addresses to a public one before transferring the information. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers.
How does NAT IP work?
Generally, the border router is configured for NAT i.e the router which has one interface in the local (inside) network and one interface in the global (outside) network. When a packet traverse outside the local (inside) network, then NAT converts that local (private) IP address to a global (public) IP address.
Why do we use NAT IP?
The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes. Routers inside the private network can route traffic between private addresses with no trouble.
What is NAT example?
For example a computer on an internal address of 192.168. 1.10 wanted to communicate with a web server somewhere on the internet, NAT would translate the address 192.168. 1.10 to the company’s public address, lets call this 1.1. 1.1 for example.
How does NAT help IP depletion?
By translating multiple private addresses carried in IPv4 headers into one unique public address, NAT allows multiple intranet users to access the Internet using only one public address, effectively mitigating public IPv4 address exhaustion.
Should NAT be disabled on router?
If NAT is turned off, the device will work on pure-router mode which can transmit data only. Please DO NOT turn it off unless your ISP supports this mode, otherwise you will lose Internet connection.
Does NAT change source IP?
NAT only translates IP addresses and ports of its internal hosts, hiding the true endpoint of an internal host on a private network. Subsequent packets from the same internal source IP address and port number are translated to the same external source IP address and port number.
