Sep 24, 2018 · From the subnet mask of 255.255.248.0 we learn that the increment is 8 therefore 172.16.8.0 is a network address which cannot be assigned to a host. Other network addresses are 172.16.16.0, 172.16.24.0, 172.16.32.0… Notice that 172.16.31.0 is a valid host address (which belongs to 172.16.24.0 to 172.16.31.255 subnet).

The subnet mask defines how large each subnet is. You can do this in binary but I’ll use decimal since it’s faster. A quick method is to take the number 256 minus the subnet mask. We are looking at the 4th octet so that’s 248: 256 - 248 = 8. We now know that each subnet has 8 addresses. Let’s start counting from 0 to show you how it Class B Space is denoted in numbers of Class C's; Ripe Subnet # of Class C's /23: 255.255.254.0: 2 /22: 255.255.252.0: 4 /21: 255.255.248.0: 8 /20: 255.255.240.0: 16 What is the maximum number of hosts per subnet for the 10.47.255.1/20 network? 4094 hosts What is the maximum valid range for IP addresses that can be assigned to hosts on the 192.168.100.248 255.255.255.248 network? Sep 24, 2018 · From the subnet mask of 255.255.248.0 we learn that the increment is 8 therefore 172.16.8.0 is a network address which cannot be assigned to a host.

Subnet Calculator is used to divide an IP network into subnetworks by calculating network address, subnet mask, broadcast address and host IP address range.Please use the form below to enter an IP address and Subnet Mask, and we'll provide you with necessary information you'll need.

A network is called a subnet when the prefix boundary contains more bits than the network's natural mask. Examples 209.60.128.0 is a class C network address with a natural mask of /24. Aug 26, 2011 · CIDR. Subnet Mask. Total IPs. Usable IPs /32: 255.255.255.255: 1: 1 /31: 255.255.255.254: 2: 0 /30: 255.255.255.252: 4: 2 /29: 255.255.255.248: 8: 6 /28: 255.255.255 D. A 240 mask is 4 subnet bits and provides 16 subnets, each with 14 hosts. We need more subnets, so let's add subnet bits. One more subnet bit would be a 248 mask. This provides 5 subnet bits (32 subnets) with 3 host bits (6 hosts per subnet). This is the best answer. So the subnet mask will be 255.255.255.248. If we use the last octet 248. 256-248 = 8, this means the last octet 0-255 is broken up into 32 groups of 8.

The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted. The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C network address of 192.168.0.192 with a subnet mask of 255.255.255

Our IP calculator takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. Normally, we setup routers dhcp with a private IP on the LAN and a subnet of 255.255.255.0 and gateway of 1.1 If the subnet was changed to 255.255.255.248, what would happen? Subnet Calculator is used to divide an IP network into subnetworks by calculating network address, subnet mask, broadcast address and host IP address range.Please use the form below to enter an IP address and Subnet Mask, and we'll provide you with necessary information you'll need. Use the information in this appendix to ensure that the outside addresses you choose are in the subnet for the appropriate subnet mask. For example, if your ISP assigns you 204.31.17.176 with a subnet mask of .240, you can see in , Subnet Number 12 for the .240 mask, that hosts can have IP addresses of 204.31.17.177 through 204.31.17.190. IP Calculator. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. Dec 19, 2019 · Subnet Mask -- A 32-bit number used to distinguish the network and host portions of an IP address. Subnet or Subnetwork -- A smaller network created by dividing a larger network into equal parts. TCP/IP -- Used broadly, the set of protocols, standards and utilities commonly used on the Internet and large networks. May 07, 2012 · These are actually fairly straightforward calculations. The easiest way to do it is to depict both the ip address and the subnet mask in binary. Take 76.127.231.231 with subnet mask 255.255.255.248 listed in binary: ip address: 01001100.01111111.11100111.11100111 subnet mask: 11111111.11111111.11111111.11111000
