IP Range Generator
Get a list of every IPv4 address in a range — either between two IPs or inside a CIDR block. Handy for firewall rules, scanning a subnet, or feeding a bulk tool. We show the full list for smaller ranges; for large ones we show a count plus a sample. Everything runs in your browser.
Generate IP Range
Choose range (start & end) or CIDR, then generate.
What Is an IP Range Generator?
An IP range is a set of consecutive IPv4 addresses. You might have a start and end (e.g. 192.168.1.1 to 192.168.1.50) or a CIDR block (e.g. 192.168.1.0/24, which is 256 addresses). This tool lists every address in that range so you can copy it into configs, scripts, or other tools. For network and broadcast addresses of a subnet, use our subnet calculator. To check if an IP is valid before adding it to a range, use IP address validator or IP list validator for many at once.
How to Use the IP Range Generator
Pick “Start & End” and enter two IPv4 addresses, or pick “CIDR” and enter something like 192.168.1.0/24. Click “Generate list”. For small ranges you get the full list; for large ones we show the total count and a sample (first and last). You can paste the result into a bulk IP lookup or IP list validator. To understand your subnet first, try subnet calculator or IP lookup for a single IP.
Features
- Start/End IP range or CIDR input
- Full list for smaller ranges; count + sample for large
- Runs in browser; no signup
- Copy-paste friendly output
Why Use This Tool
When you need an explicit list of IPs in a subnet for firewalls, scans, or documentation. Pair with subnet calculator for network design, DNS lookup for hostnames, or ping test and traceroute for connectivity checks.
FAQs
What does the IP range generator do?
It lists every IPv4 address between a start and end IP, or every address in a CIDR block (e.g. 192.168.1.0/24). You get a count and a list you can copy. For very large ranges we show a sample plus the total count.
What is the maximum range size?
We compute ranges in the browser. Very large ranges (e.g. /8) have millions of IPs and may be slow or capped for display. For big subnets, use start/end with a smaller range or check our subnet calculator for the network and broadcast addresses.
Can I use CIDR notation?
Yes. Enter something like 192.168.1.0/24 and we list all addresses in that subnet (or a sample if the range is huge).
Is it free?
Yes. Everything runs in your browser. No signup.
Why would I need a list of IPs in a range?
For firewall rules, scanning a subnet, documentation, or feeding another tool (e.g. bulk IP lookup) with a clean list. Validate the list with our IP list validator if needed.
