I'm reading Comer's TCP/IP book, where (page 107 of the 4th edition, if you're interested) he states: quote:"The IP checksum is formed by treating the header as a sequence of 16-bit integers (in ...

Figure 7-2: IP datagram and its relationship to an Ethernet II frame. Figure 7-3: IP datagram and its relationship to a IEEE 802 frame. The IP header The IP packet contains quite a few field elements.

This is in contrast to the NDN communication model that keeps datagram state at every node. IP is end-to-end while NDN is hop-by-hop, thereby enabling a per-hop stateful forwarding plane.

The current IP address scheme of 32-bit words is fast becoming inadequate. It would appear that 2 32 = 4 294 967 296 combinations of addresses should be enough for everybody, but in practice this is ...

Breaking an IP datagram (packet) into pieces in order to be sent across a transmission link with a frame size smaller than the datagram. Performed in a router, the header of the original IP packet ...

However, they usually encapsulate and encrypt the IP datagram, which contains the IP source and destination addresses. This can make them troublesome for NAT. IPSec can work in two different ways ...
