Bulk IP Validator
Paste IPv4 or IPv6 addresses separated by spaces lines commas or semicolons.
Formula used
An IPv4 address contains four eight-bit octets. Each octet ranges from zero through 255. IPv4 therefore contains 2³² possible addresses. That equals 4,294,967,296 total address combinations.
An IPv6 address contains 128 binary bits. Its theoretical space contains 2¹²⁸ combinations. This space is vastly larger than IPv4.
How to use this calculator
- Select IPv4 IPv6 or both address families.
- Choose category CIDR or IPv4 range mode.
- Enter the number of addresses required.
- Choose unique output and optional result sorting.
- Generate addresses and review their classifications.
- Copy results or download the preferred format.
IPv4 and IPv6 address types
Private IPv4 ranges support local network addressing. They are not routed across the public internet. Common blocks include 10.0.0.0/8 and 192.168.0.0/16. Another private block spans 172.16.0.0/12.
Loopback addresses reference the local device. Link-local addresses work inside a local network segment. Multicast addresses represent groups of receivers. Documentation blocks are reserved for examples and teaching.
IPv6 global unicast addresses are broadly routable. Unique local addresses serve private network roles. Link-local IPv6 addresses remain local to one link. Documentation prefixes support examples without using real hosts.
Example data table
| Example | Version | Typical type | Purpose |
|---|---|---|---|
192.168.1.74 | IPv4 | Private | Local network testing |
8.8.8.8 | IPv4 | Public | Public address example |
127.0.0.1 | IPv4 | Loopback | Local host testing |
2001:db8::10 | IPv6 | Documentation | Safe documentation example |
Developer and testing uses
Generated addresses can populate mock datasets and fixtures. They can test parsers forms and validators. They can also populate demonstration log files. Documentation ranges are safest for published examples.
Generated public-looking addresses may belong to real systems. Never assume a random public address is unused. Avoid directing traffic toward generated public addresses. Prefer documentation ranges for demonstrations and tutorials.
Frequently asked questions
Can this tool generate public IPv4 addresses?
Yes. Public mode excludes common special-use and private ranges.
Can I generate addresses inside one subnet?
Yes. Choose CIDR mode and enter your subnet.
Does the tool support IPv6 prefixes?
Yes. Host bits are randomized after your prefix.
Can I export thousands of addresses?
Yes. One request supports up to 10,000 results.
Are these addresses linked to real users?
No identity lookup occurs. The generator only creates address values.
