IPv6 lookup

The same lookup as IPv4 for IPv6 addresses, plus the announced prefix.

Parameters

Example

$ curl -H "X-API-Key: YOUR_KEY" "https://api.mygeocode.com/v1/ipv6?ip=2606:4700:4700::1111"

const url = new URL("https://api.mygeocode.com/v1/ipv6");
url.searchParams.set("ip", "2606:4700:4700::1111");
const geo = await (await fetch(url, { headers: { "X-API-Key": "YOUR_KEY" } })).json();
console.log(geo.prefix, geo.country_code);

import requests

geo = requests.get("https://api.mygeocode.com/v1/ipv6", params={"ip": "2606:4700:4700::1111"}, headers={"X-API-Key": "YOUR_KEY"}, timeout=5).json()
print(geo["prefix"], geo["country_code"])

Response fields

The same fields as the IPv4 lookup. prefix is the covering IPv6 network and version is 6, or 4 when an IPv4 address or an IPv4-mapped address (::ffff:a.b.c.d) was sent, in which case the answer is the IPv4 data.

Either version in one call

GET /v1/ip accepts an IPv4 or an IPv6 address (or none, for the caller) and returns the same record as the version-specific endpoints. Use it when you do not know in advance which kind of address you will be given.

Notes

• Accepted forms: compressed (2001:db8::1), expanded, mixed with an embedded IPv4, and with a zone index (%eth0), which is stripped.
• Calling without ip over an IPv4 connection returns the IPv4 result rather than an error, so a single call works for both.

Errors

400 invalid_request when ip is not a valid IP address, or when ips has more than 100 entries. An IPv4 address is not refused here: it is answered with the IPv4 data. In a batch, an entry that is not a valid address does not fail the call: its place in results holds "status": "error" with the address and an error object, and it is not counted.
