This article (with pictures) explains how to locate an IP Range's subnet mask, gateway, and DNS IP address
To calculate a subnet mask, network administrators determine the number of bits needed for both the network and host portions of an IP address. Once network admins determine the number of network bits, they set those bits to ones and the remaining bits to zeros for the ...
Ipcalcactually does a lot more – it takes an IP address and netmask and provides the resulting broadcast, network, Cisco wildcard mask, and host range. You can also use it as a teaching tool to present subnetting results in an easy to understand binary values. Some of the uses ofipcalca...
Re: How to set the subnet mask for ip address 220.130.17.39? The way to calculate an IP-address network and subnet mask is as follows. First you must rememember that we write IP-Addresses in decimal for our own convenience, and the computer actually sees it in binary, therf...
An interface does not add the cost to RIP routes to be received, but increases the cost by 1 for the sent RIP routes. You can run the following commands to change the cost of routes: After you run the rip metricin command, the device adds an additional metric to a received route, an...
is calculated over IP header only as the data that generally follows the IP header (like ICMP, TCP etc) have their own checksums. Now, to calculate the IP header algorithm one must know the basic header structure of IP protocol. So here is a basic format of how IP header looks like :...

Based on s, the number of bits chosen for subnetting, and m, the length of the network prefix being subnetted, calculate the following: f = m - 48 f is the number of bits within the global address prefix that are already fixed. n = 2s n is the number of network prefixes that are...
What I especially like aboutipcalcis seeing the binary form of IP addresses, which clearly shows what netmasks do. These don’t make much sense in dotted decimal notation, but in binary they are as clear as can be. A mask covers things, and in this example it’s plain that the 24-bi...
master router periodically sends messages (advertisements) to the backup routers in the virtual domain to inform them about its existence. The backup routers save the advertisement interval and VRRP priority contained in the master router advertisements to calculate the ...
