A message needs an address.

Think of a packet as a small addressed envelope. Devices pass it onward; transport protocols decide what delivery promises an application gets.

Helpful first, if these ideas are unfamiliar

These pictures are analogies to help you learn. The linked RFC explains the actual rules.

Related RFCs and changes

“Updates” changes part of an earlier RFC. “Obsoletes” replaces it. This list shows selected related documents.

KEY POINT

row=5-7 selects rows 5, 6 and 7; endpoints are included (§2.1).
row=5-* reaches the last row. The same * notation applies to columns.
Ranges extending past the document MUST be limited to its actual size (§4.2); an absent single position MUST be ignored.
