To reserve address space for the remaining address classes, all class a addresses required that the most significant bit of the high-order octet be a zero this meant that there were only 128 possible class a networks, 0000 /8 to 127000 /8, before taking out the reserved address blocks. Given the present classless nature of the ip address space, the basis for the reservation no longer applies and addresses in this block are subject to future allocation to a regional internet registry for assignment in the normal manner. It divided the address space into primarily three address formats, henceforth called address classes, and left a fourth range reserved to be defined later the first class, designated as class a , contained all addresses in which the most significant bit is zero.

Logically, a mapping of a set of ip addresses (might contain only one) to a physical interface and a single next-hop ip address ip packets whose destination address is defined as part of the set are forwarded to the next hop using the line.

In the internet addressing architecture, a private network is a network that uses private ip address space both, the ipv4 and the ipv6 specifications define private addressing ranges [1] [2] these addresses are commonly used for local area networks (lans) in residential, office, and enterprise environments. The 127000 class 'a' subnet is used for special local addresses, most commonly the loopback address 127001 this address is used to test the local network interface device's functionality. For ip to communicate with a host, the ip address must be known, and the router connected to the network on which this host is located must also know the hardware address of the housewhat if a.

An ip address is a number that represents a device like a network card uniquely on the internet or on your company's intranet this number is actually a binary one, but for convenience it's normally written as four decimal numbers. Class a addresses: the first 8 bits of the ip address are used for the network id the final 24 bits are used for the host id class b addresses: the first 16 bits of the ip address are used for the network id. The idea was that different sized organisations could be allocated a different class of ip address, to make efficient use of ip address space however, as ip networks grew, it became clear that this approach had its problems. List of ip addresses/subnets assigned to internal equipment/infrastructure along with the corresponding hostname/device name for each ip address/subnet multiple discrete networks (see nrpm 45 ) demonstrate your organization is a single entity and not a consortium of smaller independent entities.
