What is a 27 subnet mask?

/27 — 8 Subnets — 30 Hosts/Subnet. Network # IP Range. Broadcast. .0.

What is 29 IP block?

/29 represents 29 of the 32 bits of the address are the netmask hence only 3 bits are available to distinguish the computers. We have only 5 usable addresses on /29 allocations. /28 denotes the 28 of the 32 bits of the address are the netmask hence only 4 bits are available to differentiate the computers.

What does IP address 27 mean?

/27 denote that 27 of the 32 bits of the address are the netmask hence only 5 bits are available to differentiate the computers. However, you always lose 2 addresses for broadcast and loopback, so the result is: 2^(32–27) — 2 = 2⁵ -2 = 32–2 =30. We have only 30 usable addresses on /27 allocations.

What does 28 represent in a IP address?

Answer: 28 is a subnet mask. IP address has 32 bits in total. 28 denotes network ID while rest of the bits (which are 4 bits) are used for hosts.

What should my subnet mask be?

Most home networks use the default subnet mask of 255.255. 255.0. This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.

How many IP addresses are in a 29?

For example, you would request a “/29” subnet from your ISP, and you would be provided with a subnet of 8 IP Addresses, 6 of which are usable – this is because 1 is the network address (the first IP) and one is the broadcast address (the last IP).
