Here in SE NH we have a similar issue with Consolidated Communications/Fidium. Same type of situation - CC/F bought out Fairpoint who had bought Verizion"s VT-NH-ME landline business.
In our town CC ran all new fiber in 2021, we had a PPPoE 1st year (1Gb service, Zyxel router) but no ipv6. Last year CC migrated us over to Fidium (what their home fiber division is now), DHCP instead of PPPoE, used my Asus AX86U, still no ipv6. Upgraded to 2Gb service this year, bought an Asus ROG Rapture GT-AX6000, still no ipv6. CC/F says they hope to deploy it in 2024.
Sounds like even though Frontier says you have ipv6, you don't.
