IPv4 lookup

Location, timezone and network details for an IPv4 address. Leave the address out to look up the caller.

GEThttps://api.mygeocode.com/v1/ipv4

Parameters

Parameter	Type	Description
`ip`optional	string	Dotted IPv4 address. Default: the address the request came from.
`ips`optional	string	Comma-separated addresses, up to 100, for a batch. Returns `results` array in the same order. Each counts as one request.
`lang`optional	string	ISO 639-1 code for country, region and city names. Default `en`.
`key`optional	string	API key, if not sent as a header.

Example

curlJavaScriptPython

$ curl "https://api.mygeocode.com/v1/ipv4?ip=1.1.1.1"

// In a browser, with no ip parameter, this returns the visitor's own address
const geo = await (await fetch("https://api.mygeocode.com/v1/ipv4")).json();
console.log(geo.country_code, geo.timezone);

import requests

geo = requests.get("https://api.mygeocode.com/v1/ipv4", params={"ip": "1.1.1.1"}, timeout=5).json()
print(geo["country_code"], geo["org"], geo["is_datacenter"])

Response fields

Field	Type	Description
`ip`	string	The address looked up.
`version`	integer	Always 4 on this endpoint.
`country`, `country_code`	string	Name in `lang`, and the upper-case ISO 3166-1 alpha-2 code.
`region`, `region_code`	string	First-level division and its ISO 3166-2 suffix. Absent if unknown.
`city`, `postcode`	string	Best estimate. Absent if unknown.
`lat`, `lon`	number	Centre of the most specific known area.
`timezone`	string	IANA name.
`asn`, `org`	integer, string	Autonomous system number and the announcing organisation.
`is_datacenter`	boolean	Hosting or cloud range.
`is_proxy`	boolean	Known VPN, Tor or public proxy exit.
`is_private`	boolean	RFC 1918, loopback, link-local or otherwise not publicly routed. When true, the location fields are absent.

Notes

Anycast addresses such as 1.1.1.1 and 8.8.8.8 are served from many places at once. The location returned is the registered one, which is why is_datacenter is true for them.
When calling without ip through a proxy or CDN, the address seen is the proxy's. Pass the real client address in ip from your server instead.
IP data is refreshed weekly. A cache time of a day is reasonable.

Errors

400 invalid_request when ip is not a valid IPv4 address, or when an IPv6 address is sent to this endpoint (use /v1/ipv6), or when ips has more than 100 entries.
