Regardless, I'm trying to come up with a small web app that will create tables of IP addresses for each of our offices. Like say if I create a new scope for 10.1.10.0/4 it will create an array (which I can then print to a table) of: 10.1.10.0 network ID 10.1.10.1 gateway 10.1.10.2 usable 10.1.10.3 broadcast

Subnet Calculator - TunnelsUP The tool also has the ability to create a random IP address which can then be calculated. This is useful when studying and learning how to subnet and example practice networks are needed. This calculator can also be used to do reverse subnetting where the number of hosts is known but the netmask is not. Calculator is also IPv6 ready. Subnet Calculator| IP Location 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. CIDR Calculator for IPv4 addresses

The subnet which has 120 hosts would still have a subnet mask of 255.255.255.128, but now the remaining two subnets could have a subnet mask of 255.255.255.240. These would each allow 14 usable hosts, and still leave a chunk of the original /24 to be used in the future. A much more efficient use of IP …

IP Subnet Calculator . The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet. Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet IP Subnet Calculator - SubnetOnline.com Thanks to Andy Povey for developing and providing the source code for this IP subnet calculator. This is a more straightforward and faster IP subnet calculator, giving you a complete list of information concerning an IP address and Subnet Mask, including the Network and Host address size.

This Subnet Calculator can help you calculate subnet masks and ranges of IP addresses. Enter your IP address and click on the "Calculate" button above. The current address range is 192.168.106.1/24. The first usable host address is 192.168.106.1. Most admins assign this …

Jun 23, 2017 subnetting, usable IPs - Cisco Community I am trying to figure out what the usable IP range is to a class B address (172.16.1.1) with a mask of 255.255.255.0 . 172.16.1.1 /24. 2^8 -2 = 254 subnets
