How It Works

To resolve an IP address, query the TXT record (only TXT, never A or MX) of the hyphenated IP address appended to .free.query.ip2cc.com. The DNS response delivers a 2-letter ISO country code.

  1. Replace dots (.) with hyphens (-):
    2600:1f28:365:80b0:496d:ff26:8ea3:8d3 → 2600-1f28-0365-80b0-496d-ff26-8ea3-08d3
  2. Append query domain and request the TXT record:
    2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com
Important: Always execute queries via your operating system's standard recursive DNS resolver. Direct recursive sweeps or non-TXT query types on free endpoints are subject to rate limiting.

CLI Examples

dig 
$ dig +short TXT 2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com

host 
$ host -t TXT 2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com
2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com descriptive text "US"
nslookup 
$ nslookup -type=TXT 2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com
2600-1f28-0365-80b0-496d-ff26-8ea3-08d3.free.query.ip2cc.com    text = "US"
