Online IP Subnet Calculator
Wildcard mask - Wikipedia A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, they are used in several places, for example: . To indicate the size of a network or subnet for some routing protocols, such as OSPF.; To indicate what IP addresses should be permitted or denied in access control lists (ACLs).; At a simplistic level a wildcard mask can Subnet Calculator| IP Location Subnet Calculator (IPv4 Only) 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 …

Like an IP address, each section of the subnet mask address can contain any numbers from 0 to 255. For the subnet mask 255.255.255.0, the first 3 sections are full which means that device IP addresses within this subnet mask must be the same as the initial 3 sections. The last section can be any number between 0 and 255. An example best How to figure what subnet mask to use? — TechExams Community
This is a single subnet with a subnet mask of 255.255.255.0. If you started off with a range of 192.168.0.0/16 (which is the full range of private class C addresses), and you want to separate this range into /24 subnets, then this means that you can have up to 256 networks with 256 addresses (254 without network and broadcast) in each.
In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. Solved: Consider A Class C Network With The Subnet Mask 25 Consider a class C network with the subnet mask 255.255.255.41. How many network id (NID) and host id (HID) are there in the subnet mask? (A) 24,3 (B) 24, 5 (C) 20,6 (D) 20,8 IPv4 Subnet Calculator - 192.168.100.0/28 Oct 04, 2019 IP Addressing and Subnetting for New Users the "natural" Class C mask, you can denote these addresses as having a 3-bit subnet mask. Or, secondly, the mask of 255.255.255.224 can also be denoted as /27 as there are 27 bits that are set in the mask. This second method is used with CIDR. With this method, one of these networks can be described with the notation prefix/length. For example,
