They also have residential internet (AIS Fibre) and also own another ISP (CS Loxinfo). CS Loxinfo used to use their own DNS servers and such, but have switched to use the same infrastructure as AIS Fibre (sharing IP address pool and all) since 2019 or so. Also AIS mobile is IPv6 (2001:44c8:4400::/44) with CG-NAT since 2017. IIRC they were giving out /64 to every mobile client, but I'm not sure how long does /64 assignment lasts.
