4. Historical Domain Lists for .so zone

Access the archive of historical .SO domain lists and analyze how domains in the .SO namespace have evolved over time. Historical domain data helps researchers and engineers study domain growth, changes in domain-list membership, and long-term internet trends. Archive dates and coverage vary; see historical dataset access.

Coverage and methodology for .SO data

The downloadable file contains domain names from available sources, one per line in gzip-compressed plain text. It is a domain list, not a raw DNS zone file containing resource records, a WHOIS export, or a verified list of active websites.

Partial domain coverage. This dataset contains .SO domain names collected from available sources. Coverage is partial: it does not include every registered .SO domain or verify whether a website is working.

The proportion of all registered .SO domains represented in this dataset is unknown. Changes in the count may reflect both changes in the namespace and changes in collection coverage.

Additions and removals describe observed changes between dataset observations, not confirmed registrations or expirations; source changes and gaps can also affect counts. The coverage label describes the current dataset and does not establish comparable coverage across historical snapshots. Verify registration status separately before outreach, security decisions, or domain purchases.

The daily update target is 9 AM UTC. Use each file's snapshot date when scheduling imports or comparing archives; delivery can be affected by source delays. Historical availability varies by zone and date.

For reproducible analysis, record the zone, snapshot date, downloaded filename, and filtering rules. Usage is subject to our dataset license; enterprise and redistribution licensing is available separately.
