This IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more.

2021年2月12日 · With a subnet mask, devices can look at an IP address, and figure out which parts are the network bits and which are the host bits. Then using those things, it can figure out the best way for those devices to communicate.

2020年4月17日 · If you want to know what an IP address is, what's the purpose of an internet protocol address, or what's a subnet mask, read on. We're explaining it all in simple terms:

2017年4月11日 · To understand this, we must look at the devices' unique IP addresses as well as the associated subnet mask and default gateway. With these three pieces of information, we know how a device communicates with others locally as well as across an entire network.

For IPv4, a network may also be characterized by its subnet mask or netmask, which is the bitmask that, when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an IP address.

2024年9月3日 · In this Subnetting Cheat Sheet, you’ll learn all the basic to advanced subnetting concepts, including CIDR notation, and IPv4 subnet masks ranging from XX.XX.XX.XX/0 to XX.XX.XX.XX/32, IPv4 wildcard mask values, classification of IPv4 addresses from Class A to Class E, and more.

5 天之前 · The IP Subnet Calculator and IP to CIDR Converter is a quick utility that helps you calculate subnet ranges, usable IPs, and CIDR notations for IPv4 addresses. Enter any IP address and subnet mask or CIDR to get detailed results.

Quick reference crib sheet for daily subnetting tasks. You can use the IPv4 and IPv6 charts for IP address planning and to convert subnet masks to CIDR and wildcards.

Easily calculate subnet details with our free Subnet Calculator. Enter an IP and subnet mask to find network address, broadcast address, and usable host range.

2025年1月19日 · A subnet mask is a 32-bit number that separates the network and host portions of an IP address. The mask ensures that devices can determine whether an IP address belongs to the same network or a different one.
