# IP address (IPv4 or IPv6) (`ipaddr`)

Address of a network interface in the Internet Protocol: a 32-bit IPv4 address in dotted-decimal form (192.0.2.1) or a 128-bit IPv6 address in hexadecimal groups (2001:db8::1). Use this record for columns that mix both versions; ipv4 and ipv6 describe each form. The IP address of a user's device or connection can single out a person, so data protection laws such as the GDPR may treat it as personal data.

- Personal data (PII): yes
- Categories: Internet (internet), Personally identifiable information (pii)
- Countries: global

## Detection

Regular expression (Python `re`):

```
^(?:(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3}|(?:(?:[0-9A-Fa-f]{1,4}:){6}(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|::(?:[0-9A-Fa-f]{1,4}:){5}(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:[0-9A-Fa-f]{1,4})?::(?:[0-9A-Fa-f]{1,4}:){4}(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:(?:[0-9A-Fa-f]{1,4}:){0,1}[0-9A-Fa-f]{1,4})?::(?:[0-9A-Fa-f]{1,4}:){3}(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:(?:[0-9A-Fa-f]{1,4}:){0,2}[0-9A-Fa-f]{1,4})?::(?:[0-9A-Fa-f]{1,4}:){2}(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:(?:[0-9A-Fa-f]{1,4}:){0,3}[0-9A-Fa-f]{1,4})?::[0-9A-Fa-f]{1,4}:(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:(?:[0-9A-Fa-f]{1,4}:){0,4}[0-9A-Fa-f]{1,4})?::(?:[0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{1,4}|(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?:\.(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])){3})|(?:(?:[0-9A-Fa-f]{1,4}:){0,5}[0-9A-Fa-f]{1,4})?::[0-9A-Fa-f]{1,4}|(?:(?:[0-9A-Fa-f]{1,4}:){0,6}[0-9A-Fa-f]{1,4})?::))$

## Examples

- `192.0.2.1` — IPv4 address from the documentation range (RFC 5737)
- `2001:db8::1` — IPv6 address from the documentation prefix (RFC 3849)
- `192.0.2.0/24` (invalid example) — A network prefix, not an address
- `192.0.2.256` (invalid example) — The last part is larger than 255
