What are the two following addresses?

192.168.100.100

255.255.255.224

1 answer

The two addresses you've provided are an IP address and a subnet mask.

  1. IP Address: 192.168.100.100

    • This is a private IPv4 address commonly used in local networks. It's part of the IPv4 address range reserved for private use (specifically 192.168.0.0 to 192.168.255.255).

  2. Subnet Mask: 255.255.255.224

    • This subnet mask is used to determine the network and host portions of the IP address. In this case, the subnet mask 255.255.255.224 or /27 indicates that the first 27 bits are used for the network address, leaving 5 bits for host addresses.

    • This subnet mask allows for 32 IP addresses total in that subnet (2^5 = 32), but only 30 are usable for hosts (the first address is the network address and the last address is the broadcast address).

If you were using this subnet mask with the provided IP address, the network address would be 192.168.100.96, the broadcast address would be 192.168.100.127, and the usable host IP addresses would range from 192.168.100.97 to 192.168.100.126.
