What Is a Subnet Mask? A Beginner’s Guide to Subnetting
WebRemember the total Subnet Mask is 32 bits. So in binary mode our Subnet Mask is: 11111111.11111111.11111111.11111100 (First 30 bits are 1s and 2 bits are 0s) And the decimal equal of this Subnet Mask is : 255.255.255.252 . Now, let’s determine the network, broadcast and host addresses of this prefix. An IP address with Subnet Mask called ... WebGiven the Class B network: 185.85.0.0 a. How many bits are in the host field for this network? _____b. If we want to set up subnets to allow up to 100 hosts on each subnet, how many host bits must be used for host addressing? _____c. How many bits are left over that can be used for subnetting? _____d. WebJun 2, 2024 · Remember, CIDR notation describes the number of significant bits in the IPv4 address (where the significant bits are the leftmost, or unchanging bits in the subnet), and there are 32 bits in an IPv4 address, 8 for each octet. So if we have a subnet mask of 255.255.255.240, that is 16 addresses. sql or and优先级
