Mell What are the classes of IP address ranges?
Designing Your IP Addressing Scheme
| Class | Range | Network Address |
|---|---|---|
| A | 0-127 | xxx |
| B | 128-191 | xxx . xxx |
| C | 192-223 | xxx . xxx . xxx |
What is class field in IP address?
TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class has a range of valid IP addresses. For the IP addresses from Class A, the first 8 bits (the first decimal number) represent the network part, while the remaining 24 bits represent the host part.
How do I find my first and last IP address?
Add one address to the subnet address to find the first usable IP address. 2. Subtract one address from the broadcast address to find the last usable IP address. The following table shows all of the new possible subnets; the usable range of IP addresses for each subnet; and the broadcast address for each subnet.
What is the range of Class B IP addresses?
Class B IP address always has its first bits as 10, next 14 bits as a network address and following 16 bits as the host address. The range of IP addresses is 128.0.0.0 to 191.255.255.255. This means that it allows 2^14 networks and 2^16 hosts per network. This class of IP address is used for a medium network like multinational companies.
What is the default IP address for Class A?
The IP range 127.x.x.x is reserved for loopback IP addresses. The default subnet mask for Class A IP address is 255.0.0.0 which implies that Class A addressing can have 126 networks (2 7-2) and 16777214 hosts (2 24-2).
How are the classes of IPv4 addresses identified?
Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. All the five classes are identified by the first octet of IP Address. Internet…
What is the decimal number in a class IP address?
In a B class IP address, the binary addresses start with 10. In this IP address, the class decimal number that can be between 128 to 191. The number 127 is reserved for loopback, which is used for internal testing on the local machine. The first 16 bits (known as two octets) help you identify the network.
