CIDR (Classless Inter-Domain Routing, sometimes known as supernetting) is a way to allocate and specify the internet addresses used in inter-domain routing more flexibly than with the original system of Internet Protocol (IP) address classes. As a result, the number of available Internet addresses has been greatly increased. CIDR is now the routing system used by virtually all gateway hosts on the Internet's backbone network. The Internet's regulating authorities now expect every Internet service provider (ISP) to use it for routing.

When was CIDR-FM created?
CIDR-FM was created in 1948-09.
What two advantages does cidr provide to a network?
The advantages of CIDR over the classful IP addressing are: # CIDR can be used to effectively manage the available IP address space. # CIDR can reduce the number of routing table entries. # CIDR can be used to effectively manage the available IP address space. # CIDR can reduce the number of routing table entries.
Why did the ietf introduce cidr and what does cidr stand for?
To help reduce the providers interfacing directly into the Internet. Classless routing.
What does CIDR stand for and when was it founded?
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing Internet Protocol packets, Or (CIDR) The Center for Inherited Disease Research, that was founded in 1997.
What is the default mask for class A in CIDR notation?
2
If you have a subnet mask of 255.255.240.0 what would the cidr notation be?
The subnet mask of 255.255.240.0 corresponds to a CIDR notation of /20. This is because the mask has 20 bits set to 1 in its binary representation (11111111.11111111.11110000.00000000). Thus, the CIDR notation for this subnet is 192.168.0.0/20, assuming a starting IP address of 192.168.0.0.
If you have a subnet mask of 255.255.240.0. what would the CIDR notation be?
The subnet mask 255.255.240.0 corresponds to a CIDR notation of /20. This is calculated by converting the subnet mask to binary, where there are 20 consecutive '1's followed by 12 '0's. Therefore, the network prefix in CIDR notation is represented as /20.
What is the cidr of ipv4 address of 123.54.34.77?
To determine the CIDR (Classless Inter-Domain Routing) notation for the IPv4 address 123.54.34.77, you need to know the subnet mask associated with it. If the subnet mask is not provided, a common default for a public IP address like this would be /24, which indicates that the first 24 bits are used for the network portion. Thus, the CIDR notation could be represented as 123.54.34.77/24. However, the actual CIDR can vary depending on the specific subnetting of the network.
In CIDR conventional network class distinctions do not exist?
True, they do not exist.
What CIDR notation takes the form of the network ID?
forward slash
What would the value of the last octet of the subnet mask be if the CIDR notation for an address is 192.168.1.1627?
This isn't a valid CIDR address, so I assume it is: 192.168.1.162/7 That would yield a subnet mask of 255.255.255.254
What is the alternate notation for a Class C subnet?
/24 in CIDR 255.255.255.0 in netmask.
