Does Frontier Fiber (Verizon) use CGNAT?
Short answer: Sometimes. Frontier Fiber (Verizon) uses CGNAT on some plans or in some areas, according to Frontier Fiber (Verizon)'s own documentation. IPv6 is only available in some areas.
Can I self-host on Frontier Fiber (Verizon)?
Frontier is now covered by Verizon's customer agreement.
| CGNAT by default? | Some plans/areas Confidence: High: stated on the ISP's own page. Frontier's network management policy says your IP may be public or a CGN (carrier-grade NAT) address. It doesn't say which customers get which; community posts suggest most fiber lines get a public dynamic IPv4. Frontier's internet services are configured to use an internet protocol address, which may be a publicly-routable Internet protocol address or a privately managed IP address utilizing CGN (Carrier Gateway NAT) technology.
