How does port address translation work?

Port Address Translation (PAT) is an extension of Network Address Translation (NAT) that permits multiple devices on a LAN to be mapped to a single public IP address to conserve IP addresses. If another computer logs on the Internet, this device assigns it the same public IP address, but a different port number.

Can you send an email to an IP address?

Are IP addresses Geographic?

IP addresses on computer networks do not represent specific geographic locations. It is still theoretically possible, however, to determine the physical location of IP addresses in many (but not all) cases.

What is Port Address Translation also known as?

Port Address Translation (PAT), is an extension to network address translation (NAT) that permits multiple devices on a local area network (LAN) to be mapped to a single public IP address. Port Address Tranlation is also called porting, port overloading, port-level multiplexed NAT and single address NAT.

What is the difference between NAT and PAT?

The main difference between them is that NAT is used to map public IP addresses to private IP addresses, it could be a one-to-one or many-to-one relation. On the other hand, PAT is a type of NAT where the multiple private IP addresses are mapped into a single public IP (many-to-one) by using ports.

Does Gmail include IP address?

Are IP addresses used in the lower layers of Ethernet?

In fact, at the lower layers of the Ethernet protocol, IP addresses are not even used. All network addresses are translated into MAC addresses. To find a remote workstation’s MAC address, the Address Resolution Protocol (ARP) is used.

How does the Postal Service deliver a letter?

The internal workings of the Postal Service takes care of the rest and the letter is delivered, usually without any further involvement on the part of the sender. The remote packet delivery example is oversimplified, but you see how important IP addresses are to the packet delivery process.
