What does 24 mean in IP address?

This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated.

How do you calculate the number of subnets?

Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.

What is a 255.255 254.0 subnet? = 23 bits mask = 510 hosts (512 -2 ) = 22 bits mask = 1022 hosts (1024 -2 ) = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)

What does 24 mean in subnetting?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

What does 28 mean in IP address?

It’s a subnet mask. IP address has 4 octets of 8 bits each and 32 bits in total. 28 means, first 28 bits denote network ID while 4 bits are used for hosts or they identify the hosts.

Which of the following is the best definition of IP spoofing?

IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.

Is 255.255 255.255 IP address valid?

No 255.255. 255.255 can’t be allocated to a host, because it is used as limited broadcast address(destination) i.e. when any host wants to broadcast information to all the hosts in its entire network it will assign the destination ip as 255.255. 255.255(ie send to all).
