Question: What Is The CIDR Value Of Class B?

What is 192.168 called?

1.1 – Computer Definition.

The common default IP address of a router.

Although it can be changed to another private IP addressing space, most of the time, the 192.168 range is used, and the default router address is left as is..

What is the Private IP range of Class B?

How is CIDR value calculated?

The formula to calculate the number of assignable IP address to CIDR networks is similar to classful networking. Subtract the number of network bits from 32. Raise 2 to that power and subtract 2 for the network and broadcast addresses. For example, a /24 network has 232-24 – 2 addresses available for host assignment.

What is a Class B IP address?

Class B Address An IP address which belongs to class B has the first two bits in the first octet set to 10, i.e. Class B IP Addresses range from 128.0. x.x to 191.255. x.x. The default subnet mask for Class B is 255.255. … Class B has 16384 (214) Network addresses and 65534 (216-2) Host addresses.

What does CIDR 32 mean? /32 is the CIDR (shorthand) and refers to how many 1’s are in the subnet mask. For /32 that is or 11111111.11111111.11111111.1111111. that means you can only have one ip address, on your network before needing a gateway/router to get outside that network.

What is class B private address?

255.255. Class B: 172.16. 0.0 to 172.31. 255.255.

What is a class B subnet?

In a Class B address, the first two octets are the network portion, so the Class B example in Figure 1 has a major network address of 128.0. 0.0 – 191.255. 255.255. Octets 3 and 4 (16 bits) are for local subnets and hosts. Class B addresses are used for networks that have between 256 and 65534 hosts.

What is a 192.168 IP address?

192.168. 1.1 is a common factory IP address for a consumer-grade router. If the router is used for connecting to the Internet then all computers and devices which access the Internet through it will use this address as their default gateway.

How do I know if my IP is public or private?

Public IP address are the IP addresses which have to registered before use. IANA is responsible for register these IP addresses to the organizations. Private IP address are the IP addresses which are reserved by IANA and they are not routable in the internet. These addresses will be not assigned to any organizations.

What is CIDR value?

CIDR notation is a compact representation of an IP address and its associated routing prefix. The notation is constructed from an IP address, a slash (‘/’) character, and a decimal number. The trailing number is the count of leading 1 bits in the routing mask, traditionally called the network mask.

What is the default mask for Class B in CIDR notation?

Default Subnet MaskIP Address ClassDefault Subnet MaskClass A255.0.0.0Class B255.255.0.0Class C255.255.255.0

What is a class B network?

Class B networks are defined as being between 128.0. 0.0 and 191.255. 255.255. In modern CIDR notation, a class B network would have the subnet mask /16, there would be a total of 16,384 possible networks and 65,536 possible individual host IP addresses per network.
