IP Address Extractor

The IP address extractor scans text or log output for IPv4 and IPv6 addresses, returns a de-duplicated list, and can separate private and reserved ranges from public addresses so you can focus on external traffic.

How to use the IP Address Extractor

  1. Paste log output or any text containing addresses.
  2. Choose whether you want IPv4, IPv6 or both.
  3. Exclude private ranges if you only care about external traffic.
  4. Copy or download the list.

Example

Input
Requests from 203.0.113.9 and 192.168.1.10
Output
203.0.113.9   (public)
192.168.1.10  (private)

Common use cases

  • Pulling client addresses out of a web-server access log.
  • Collecting the addresses that appear in a firewall rule set.
  • Separating internal from external hosts in a network capture summary.

Limitations and things to watch for

  • IPv4 matching validates each octet is 0–255, so a version string such as 1.2.3.400 is not returned. Version numbers that happen to be valid octets, such as 10.0.0.1, cannot be distinguished from addresses.
  • IPv6 matching covers the standard forms including compressed notation and IPv4-mapped addresses, but not every exotic textual representation in the specification.
  • Private and reserved detection follows RFC 1918, RFC 4193, loopback, link-local and documentation ranges.

Frequently asked questions

Does it recognise IPv6 addresses?
Yes, including compressed notation with a double colon and IPv4-mapped addresses. You can also restrict the results to one family.
What counts as a private address?
The RFC 1918 ranges (10/8, 172.16/12, 192.168/16), loopback, link-local, carrier-grade NAT, documentation ranges, and the IPv6 unique-local and link-local ranges.
Are the addresses looked up or sent anywhere?
No. Extraction is a local pattern match. If you want details about a specific address, the IP lookup tool does that separately and tells you that it is server-side.
