Classless Inter-Domain Routing - Wikipedia A subnet mask is a bitmask that encodes the prefix length associated with an IPv4 address or network in quad-dotted notation: 32 bits, starting with a number of 1 bits equal to the prefix length, ending with 0 bits, and encoded in four-part dotted-decimal format: A subnet mask encodes the same information as a prefix length but Chapter 4 -Subnetting - review Flashcards | Quizlet D. A 240 mask is 4 subnet bits and provides 16 subnets, each with 14 hosts. We need more subnets, so let's add subnet bits. One more subnet bit would be a 248 mask. This provides 5 subnet bits (32 subnets) with 3 host bits (6 hosts per subnet). This is the best answer. How to subnet an IPv4 /24 - Rob's Server

CIDR, Subnet Masks, and Usable IP Addresses Quick Aug 26, 2011 Wildcard mask - Wikipedia A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, they are used in several places, for example: . To indicate the size of a network or subnet for some routing protocols, such as OSPF.; To indicate what IP addresses should be permitted or denied in access control lists (ACLs).; At a simplistic level a wildcard mask can Available Hosts per Subnet network network mask hosts networks total hosts /count possible available ; 24: 256: 254: 1: 254: 25: 128: 126: 2: 252: 26: 255.255 Subnet Calculator| IP Location
