.comcast Domain Information

Country flagLogo for .comcast Domain

Cable television, broadband, and telecommunications framed the .comcast application in ICANN's 2012 New gTLD Program. Broadband providers brought a distinctive exposure to the round: they combine very large residential subscriber bases with monthly billing, equipment returns, and technical support — three processes that generate routine customer contact and are therefore reliable pretexts for phishing built on lookalike domains.

Service providers of this scale also carry email hosting for millions of legacy accounts, which extends the credential-theft surface well beyond the billing relationship itself. A closed extension addresses both by removing the registration route entirely. The extension is not currently active in the DNS root zone and cannot be registered by any party.
