The Backbone of Facebook's Online Presence
In the vast world of the internet, domain nameservers quietly power how websites load and connect users across the globe. One such essential player is b.ns.facebook.com, a nameserver that has been supporting facebook.com and its related domains for nearly three decades.
A Look at Its Registration History
The domain b.ns.facebook.com was created on March 29, 1997. It remains active with an expiration date set for March 30, 2034. Its registrar is RegistrarSafe, LLC, and the WHOIS server is whois.registrarsafe.com. Status flags such as clientDeleteProhibited and serverTransferProhibited help protect it from unauthorized changes.
Technical Specifications and Location
Current DNS records show an IPv4 address of 129.134.31.12 located in the United States under AS32934 Facebook, Inc. An IPv6 address of 2a03:2880:f0fd:c:face:b00c:0:35 is also assigned to the same organization. A TXT record with "v=spf1 a ~all" helps with email security practices.
This nameserver works alongside others including a.ns.facebook.com, c.ns.facebook.com, and d.ns.facebook.com to ensure reliable resolution for Facebook's vast network of services.
What It Offers
As part of Facebook's infrastructure, b.ns.facebook.com handles domain name system queries that direct traffic to the correct servers. It does not host a public website but serves a critical behind-the-scenes role for one of the world's largest social platforms.
Recent updates to its records occurred as recently as April 2026, confirming its ongoing maintenance and stability.
A light note: without nameservers like this, even the biggest online destinations could face unexpected hiccups in connectivity.
