Does it publish a geofeed?

Yes for the range we sampled (173.16.20.0 – 173.17.63.255): its registry record links an RFC 8805 geofeed at https://mediacomcable.com/.rest/geofeed/v1/download. Location vendors that follow RFC 9632 can read where each of these ranges is used, so a wrong city here can be fixed at the source. Checked 2 Nov 2026.

Shared addresses (CGNAT)

Mediacom hasn’t been documented as using carrier-grade NAT in a source we could check. To see whether your own connection is behind it, compare your router’s address on the CGNAT check.

IPv6

DB-IP lists 94 IPv6 ranges for AS30036, so customers can get IPv6 addresses, which databases place separately from IPv4.
