Unveiling a Persistent DNS Player
The domain ns-520.awsdns-01.net has been active for 15 years, first registered on October 21, 2010. It remains fully operational with an expiration date set for October 21, 2026. Managed through registrar MarkMonitor Inc., the domain carries multiple status flags including clientDeleteProhibited, clientTransferProhibited, and serverDeleteProhibited, which help maintain its stability.
DNS and Technical Profile
Its nameservers point to a cluster within the same awsdns-01.net family: g-ns-1345.awsdns-01.net, g-ns-1921.awsdns-01.net, g-ns-450.awsdns-01.net, and G-NS-771.AWSDNS-01.NET. DNSSEC is not enabled. The domain resolves to IPv4 address 205.251.194.8 and IPv6 address 2600:9000:5302:800::1, both hosted in the United States under AS16509 amazon.com, Inc.
These details align with the structure of Amazon Route 53 name servers, which commonly follow the ns-###.awsdns-##.net pattern. The IP addresses are located in the Chicago area according to GeoIP data updated as recently as April 2026.
What the Data Reveals
No registrant details beyond the registrar appear in public WHOIS records, so ownership remains not publicly disclosed. The domain shows no active web content when accessed directly, consistent with its role as a dedicated nameserver rather than a public website. Recent updates to the record occurred on July 31, 2025, and the WHOIS server is whois.markmonitor.com.
This setup underscores the domain's function in supporting reliable DNS resolution across potentially thousands of hosted zones, as similar entries appear in lists of Route 53 infrastructure. Its longevity and protected status highlight the emphasis on uptime in large-scale DNS operations.
While the exact services tied to this specific nameserver instance are not detailed in public records, the configuration fits standard practices for authoritative DNS hosting.
