# Same Name Servers in WHOIS The domains whose WHOIS record names the same name servers as wikipedia.org (ns0.wikimedia.org to ns2.wikimedia.org): 955. Source: https://docs.deepinfo.com/reference/discovery/associated-domain-finder/examples/whois-ns/ Last updated: 2026-09-26 --- `GET https://api.deepinfo.com/v1/discovery/associated-domain-finder?domain=wikipedia.org&association=whois_ns&page_size=25` The domains whose WHOIS record names the same name servers as wikipedia.org (ns0.wikimedia.org to ns2.wikimedia.org): 955. Example 7 of 11 in **One Association Type** · [Associated Domain Finder Examples](/reference/discovery/associated-domain-finder/examples/) · endpoint: [Associated Domain Finder](/reference/discovery/associated-domain-finder/) Tags: `param` `association` · `param` `domain` · `value` `whois_ns` · `value` `wikipedia.org` `association=whois_ns` compares the name servers listed in the WHOIS record, which the registry publishes. The API found 955 domains on `ns0`, `ns1` and `ns2.wikimedia.org`, such as `se.wiki` and `wikiversity.community`. The WHOIS list can differ from the live DNS: the first record shown has no DNS data at all. In the response, look at `results[].domain.whois.name_servers` and `results[].dns.ns`. ## Request | Parameter | In | Value | |---|---|---| | `domain` | query | `wikipedia.org` | | `association` | query | `whois_ns` | | `page_size` | query | `25` | ```bash curl 'https://api.deepinfo.com/v1/discovery/associated-domain-finder?domain=wikipedia.org&association=whois_ns&page_size=25' \ -H 'apikey:
