Frequent question: What is the subnetwork number of a host?

What is the subnetwork address for a host?

The host is in the 64 subnet.

How do you determine the network number of a host?

The formula for determining the number of hosts a network supports is 2n-2, where n is the number of bits used for the host.

  1. 2n-2 is sometimes expressed as (2^n) – 2. Both indicate 2 raised to the power of n.
  2. You subtract two to reserve one IP for the network ID and one for the broadcast address.

What is the subnetwork number of a host with an IP address of 172.16 66.0 21?

What is the subnet id of a host with an IP address 172.16. 66.0/21? Explanation: A /21 is 255.255. 248.0, which means we have a block size of 8 in the third octet, so we just count by 8 until we reach 66.

Why is subnet mask always 255?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. … The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address. Neither can be assigned to hosts, as they are reserved for these special purposes.

How many subnets and hosts does the network address of 172.16 0.0 19 provide?

The network address of 172.16. 0.0/19 provides how many subnets and hosts? 7 subnets, 30 hosts each.

What is the maximum number of IP address that can be assigned to hosts on the local subnet that uses the 255.255 255.224 subnet mask?

The subnet mask defines the number of hosts available on a subnet. The mask 255.255. 255.224 leaves five bits for the host address, which could theoretically hold 32 addresses.

What is the first valid host on the subnetwork that the node 172.30 190.198 24 belongs to?

Which class of IP address provides a maximum of only 254 host addresses per network ID?

9. Which class of IP address provides a maximum of only 254 host addresses per network ID? Explanation: A Class C network address has only 8 bits for defining hosts: 28 – 2 = 254.

What is the broadcast address of 192.168 192.10 29?

What is the maximum number of IP address?

Addresses in IPv4 are 32-bits long. This allows for a maximum of 4,294,967,296 (232) unique addresses. Addresses in IPv6 are 128-bits, which allows for 3.4 x 1038 (2128) unique addresses. The total usable address pool of both versions is reduced by various reserved addresses and other considerations.
