Ip Address Classes شرح

The other two classes are used for other purposes class d for multicast and class e for experimental purposes.

Ip address classes شرح. Examples of class a ip address are. 1 2 3 4 10 20 30 45 125 234 123 23 126 100 200 45 etc. To find the class of an ip address simply pay attention on the first octet. Tcp ip defines five classes of ip addresses.

Represented in decimal as 1 to 126 with a binary representation of 0xxxxxxx. This class allows for a maximum of 128 network hosts. Internet protocol hierarchy contains several classes of ip addresses to be used efficiently in various situations as per the requirement of hosts per network. Following are the different classes of ip address.

Ip classes an ip class is a complete range of ip addresses that are designed to provide an addressing scheme that can accommodate small and large scale networks. An ip address internet protocol address is a numerical representation that uniquely identifies a specific interface on the network addresses in ipv4 are 32 bits long. The class is determined by the value of the first octet. There are 5 classes that are defined by internet assigned numbers authority iana as follows.

بداية يجب شرح مجموعة من المصطلحات التي يجب التعرف عليها لشرح وفهم ما هو ip address والتي تتمثل في. Ip addresses from the first three classes a b and c can be used for host addresses. Some ip addresses are reserved for specific uses for example 127 0 0 1 is always utilised as localhost rfc 3330. This class ip address always has its first bit as 0 next 7 bits as a network address and following 24 bits as the host address.

This allows for a maximum of 4 294 967 296 2 32 unique addresses addresses in ipv6 are 128 bits which allows for 3 4 x 10 38 2 128 unique addresses. All the five classes are identified by the first octet of ip address. The value of the first octet determines the class. Class a b c d and e.

On the basis of this division ip addresses are classified into various classes. The total usable address pool of both versions is reduced by various. Each class has a range of valid ip addresses. Class c networks وهو هذا النوع من الشبكات التي تتكون من عدد قليل من الأجهزة وفي هذا النوع من.

Different classes of ip address. If the value of first octet is in range 1 to 127 it s a class a ip address. If the value of first octet is in range 128 to 191 it s a class b ip address.
