What is the size of source and destination IP address on IP header ?
Answer: D
The source and destination addresses are 32 bits each.
In the IPv4 header, the source address and destination address fields are each 32 bits (4 bytes), written in dotted decimal as four 8-bit numbers, such as 192.168.1.1.
4 bits is the size of the version and header length fields, 8 bits that of the time-to-live and protocol fields, and 16 bits that of the total length and checksum fields. (IPv6 addresses are 128 bits.)
