Hi, a 4g/5g provider in Germany(1&1) provides a nat64 gateway without providing the nat64 prefix via DNS64 (it is the well known 64:ff9b::/96) Is there a known way, how the provider could tell the user equipment the pref64? (via RA ? ) rfc/3ggp paper? https://modemmanager.org/docs/modemmanager/ip-connectivity-setup-in-lte-modems/ Regards, Thomas
