IPv6 Security Issues Internet Protocol v6 (IPv6) is replacing Internet Protocol v4 (IPv4). The need for IPv6 has risen to the forefront due to the depletion of IPv4 addresses. Security concerns and issues have slowed the adoption of the new protocol. Trade information is readily available for IPv6. A simple web search on the topic will lead you to trade magazine articles‚ books‚ white paper and even the government agency recommendations. The marketplace is brimming with “solutions” to IPv6 security

The mask number represents the number of 1s in the binary of the address that is ’masked" against the address so that it ignores the last bits which are for the group of IP addresses in the masked address. The first address of a subnet block (all 0s) is called the network address or network ID. The last address (all 1s) is the broadcast address of the network. Typically the network address +1 or the broadcast address -1 is the gateway to the internet. The ’slash’ notation (ie /24) is known

belong to a subnet are addressed with a common‚ identical‚ most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields‚ a network or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface. The routing prefix is expressed in CIDR notation. It is written as the first address of a network‚ followed by a slash character (/)‚ and ending with the bit-length of the prefix. For
