Calculate subnet details, network and broadcast addresses, and host ranges
An IPv4 subnet calculator is a friendly ip address calculator that breaks a network into predictable chunks. Instead of juggling math for every ip range and subnet mask, the tool shows the network address, broadcast address, wildcard mask, and usable host range the moment you enter an IP and prefix. It behaves like a super-charged ip subnet calculator combined with a cidr calculator, netmask calculator, and inverse mask calculator, all wrapped in one page.
Under the hood, the calculator follows the same formulas network engineers use for subnetting mask calculations, VLSM planning, and CIDR aggregation. You can explore dotted-decimal masks such as 255.255.255.0, toggle cidr notation like /26, or paste a custom mask to see how many hosts fit into the subnet. Because the tool is browser-based, nothing is uploaded; you can explore ip range from subnet, subnet mask range, and even wildcard conversions safely on your own machine.
The calculator also helps bridge the gap between IPv4 and IPv6. When you understand how an ipv4 subnet calculator works, moving to an ipv6 subnet calculator or ip6 subnet calculator becomes much easier because the same concepts—prefix length, network boundary, and host math—still apply. Think of it as a translator between human-readable addressing and the binary logic that routers live by.
Whether you are calculating ip address plans for a new office, double-checking an access list, or studying for certifications, having this ipv4 subnet mask calculator on hand saves time and prevents costly typos. It keeps your cidr calculator ipv4 work accurate, your ip range calculator notes tidy, and your documentation consistent.
Start by typing the IP network you want to explore. You can paste 10.10.4.0, 172.16.8.0, or any other subnet. Choose a subnet mask from the dropdown or drag the CIDR slider to the prefix you need. The tool accepts dotted masks, CIDR notation, or custom values, so you can mimic any ip address subnet calculator workflow.
Click “Calculate” to instantly view the network address, broadcast address, first and last usable hosts, and wildcard mask. The results grid works like a visual subnet calculator, so you can map ip range and subnet mask combinations without digging through spreadsheets.
Need documentation? Export to CSV or JSON for change records. Want to try another prefix? Slide to /27, paste a VLSM mask, or hop into the CIDR calculator link. It’s the fastest way to compare sub mask ip values, calculate ipv6 subnet equivalents, or double-check ip range mask calculator notes before you deploy.
Skip manual math. The calculator instantly shows network, broadcast, cidr range, and host counts so you can size VLANs, VPNs, or DMZs in seconds.
Every formula follows RFC standards, reducing typos that could break routing tables, ACLs, or firewall policies.
Plan legacy IPv4 networks and explore ipv6 subnet calculator tips from the same interface so migrations stay consistent.
See how a /28 compares with a /22, generate subnet charts, and document classless subnet calculator output for reuse later.
Need proof for a change ticket? Export ip address range calculator data to CSV or JSON and attach it to your approval workflow.
Every section uses plain language, so even beginners can understand subnet mask for ip address logic without wading through jargon.
Instantly convert between /24 and 255.255.255.0, or any other pair, making calculate cidr from subnet mask tasks effortless.
See the first and last usable hosts, total host count, and wildcard mask—perfect for ip range and subnet mask planning.
Convert any subnet to a wildcard in one click, ready for ACLs or route-maps, so you never mis-type a wildcard subnet mask calculator value.
View IP, mask, and broadcast values in binary to understand how the bits flip—ideal for subnet bit calculator study sessions.
Jump to the IPv6 calculator, CIDR calculator, range calculator, or wildcard mask calculator without leaving the page.
Once loaded, the calculator continues working even without internet access, so field engineers can check subnets on-site.
Quickly compare /30 links versus /26 office networks so you can allocate ip address ranges without waste.
Export subnet calculator cidr details to share with cloud teams, MSP partners, or compliance reviews.
Paste an address to see whether it really belongs to the subnet in question. No more guessing if a DHCP scope overlaps.
The human-written explanations make it easier to prepare for certification exams that cover ip subnet converter math and CIDR notation.
Verify that an ip range calculator online result matches your firewall policy before you push changes to production.
