Some nomenclature used to describe prefixes:
126.96.36.199 This is an address since it has no associated mask
188.8.131.52/24 This is a prefix.
184.108.40.206/32 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, 220.127.116.11/28 is more specific than 18.104.22.168/24. A less specific prefix that overlaps with a more specific is the covering prefix. For example, 22.214.171.124/24 is the covering prefix for 126.96.36.199/28 and 188.8.131.52/28 is termed the covered prefix. A covering prefix is therefore always less specific than its covered prefixes.
