Name

Destination IP Address

Synopsis

Identifies the 32-bit IP address of the final destination for the IP datagram.

Size

Thirty-two bits.

Notes

This field identifies the final destination for the datagram, but does not necessarily identify the next router that will receive this particular packet. IP’s routing algorithms are used to identify the next hop, which is determined by examining the Destination IP Address and comparing this information to the local routing table on the local system. In order for a packet to be delivered to the final destination system, that system’s IP address must be provided in the header and must always remain in the header.

Capture Sample

In the capture shown in Figure 2.21, the Destination Address is shown as Bacteria, which is 192.168.20.50 (or hexadecimal “c0 a8 14 32”).
