The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination. Each gateway computer on the network checks this address to see where to forward the message. Even though some packets from the same message are routed differently than others, they’ll be reassembled at the destination.

Time To Live, how many times a packet can be passed from one computer to another while in transit on the Internet. TTL is a value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded. For a number of reasons, packets may not get delivered to their destination in a reasonable length of time. For example, a combination of incorrect routing tables could cause a packet to loop endlessly. A solution is to discard the packet after a certain time and send a message to the originator, who can decide whether to resend the packet. The initial TTL value is set, usually by a system default, in an 8-binary digit field of the packet header.
Also known as “port forwarding,” the transmission of data intended for use only within a private network through a public network in such a way that the routing nodes in the public network are unaware that the transmission is part of a private network, as commonly done when connecting to a private network over the Internet using Virtual Private Networking.
