What is in it

Included

  • Every registered .ee domain name we know of: registered names only, no subdomains. Internationalised names are written in their xn-- form.
  • The date each name first appeared in the dataset.
  • The IPv4 and IPv6 addresses the name pointed to in the last 90 days.
  • For each address: the network number (ASN), the network name and the country the network is registered in.
  • The name servers of each name.

Not included

  • No open ports or services.
  • No vulnerabilities and no software versions.
  • No scan data: nothing about what runs at the addresses.
  • No owner or contact details, no personal data.
  • No mail server records in this version.

Verify

Check a download against the published checksums, then unpack it.

curl -O https://osn.lt/downloads/ee/ee-domains.json.gz
curl -O https://osn.lt/downloads/ee/SHA256SUMS
sha256sum -c SHA256SUMS --ignore-missing
gunzip -k ee-domains.json.gz
  • --ignore-missing skips the files you did not download; each file you did should print OK. On macOS: shasum -a 256 -c SHA256SUMS.
  • gunzip -k keeps the .gz file next to the unpacked one.

Formats

Example record. The address is a documentation address, not a real one.

JSON

One document: generation time, count and an array of records.

{
  "generated_at": "2026-10-26T05:12:03Z",
  "count": 123456,
  "domains": [
    {
      "domain": "example.ee",
      "first_seen": "2026-05-27",
      "a": [
        { "ip": "192.0.2.10", "asn": 64500,
          "as_name": "Example Network", "country": "EE" }
      ],
      "aaaa": [],
      "ns": ["ns1.example.ee", "ns2.example.ee"]
    }
  ]
}

XML

The same records as elements and attributes. UTF-8, values escaped.

<?xml version="1.0" encoding="UTF-8"?>
<domains generated_at="2026-10-26T05:12:03Z" count="123456">
  <domain name="example.ee" first_seen="2026-05-27">
    <a ip="192.0.2.10" asn="64500"
       as_name="Example Network" country="EE"/>
    <ns>ns1.example.ee</ns>
    <ns>ns2.example.ee</ns>
  </domain>
</domains>

TXT

One name per line, sorted, UTF-8. Internationalised names are in their xn-- form.

example.ee
xn--un-bka.ee

When the network of an address is unknown, asn is 0 and as_name and country are empty.
