.EDU domain list & statistics

Coverage and methodology for .EDU data

Partial domain coverage. The .EDU registry does not publish its complete zone file. This dataset contains .EDU domain names collected from available sources; it does not include every registered .EDU domain, and presence in the list does not confirm a working website. The proportion of all registered .EDU domains represented in the dataset is unknown.

Monthly totals. Each month's total is the domain count on the last available day of that month; the current month shows the latest snapshot. Changes in the count may reflect both changes in the namespace and changes in collection coverage.

New domains. Each day's list is compared with the previous snapshot, and names that appear are counted as new. Monthly figures are sums of these daily counts. The first month of data and the current month are partial and marked in the tables.

Expired domains. A domain missing from a snapshot may have expired or may only be missing from our sources. Without the complete zone file the two cannot be told apart, so expired and removed .EDU domains are not reported yet.

Freshness. 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.

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.
