The IPv4 header length is typically how many bytes?

Explanation:
IPv4 header length is determined by the IHL field, which counts 32-bit words in the header. The minimum IHL is 5 words, equal to 20 bytes, which is the header size when no options are present. If options are included, the header grows in 4-byte increments up to 60 bytes. Since the typical, no-options header is 20 bytes, that is the correct answer.
