Comcast Corporation

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

  • Television: Cable TV and streaming services including Peacock
  • Phone: VoIP and mobile phone services
  • Business Services: Enterprise networking, data centers, and managed services
  • Media & Entertainment: NBCUniversal studios, theme parks, and broadcast networks

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.
