Comcast Corporation

Comcast Corporation is one of the largest telecommunications and media conglomerates in the United States.

The company operates primarily through its Xfinity brand for consumer services and NBCUniversal for media and entertainment.

Technical Infrastructure

The domain operates its own authoritative DNS infrastructure with five nameservers (dns101-105.comcast.net), all hosted on Comcast's backbone network with full IPv4 and IPv6 support.

The domain is DNSSEC-signed and maintains extensive TXT records for third-party service verification including AWS, Google, Docker, and Adobe integrations.
