AS7015 is one of Comcast Cable Communications' regional networks, part of the Xfinity residential broadband footprint in the United States.

What it's used for

• Cable and fibre home internet for US households in Comcast's service regions.

Notable

Interesting

• Comcast splits its consumer footprint across multiple ASNs for regional routing, all serving the same Xfinity service.
