-Prefixes
-^^^^^^^^
-
-Some nomenclature used to describe prefixes:
-
-* 1.1.1.1 This is an address since it has no associated mask
-* 1.1.1.0/24 This is a prefix.
-* 1.1.1.1/32 This is a host prefix (the mask length is the size of the address).
-
-Prefix A is more specific than B if its mask length is longer, and less specific if
-the mask is shorter. For example, 1.1.1.0/28 is more specific than 1.1.1.0/24. A
-less specific prefix that overlaps with a more specific is the **covering** prefix.
-For example, 1.1.1.0/24 is the covering prefix for 1.1.1.0/28 and 1.1.1.0/28 is termed
-the **covered** prefix. A covering prefix is therefore always less specific than its
-covered prefixes.
