IPV6 settings for ASUS RT-N66U Router


#1

What is the appropriate IPV6 connection type to use in the setup of the IPV6 settings of an ASUS RT-N66U router to utilize Cloudflare’s DNS servers?

I have an ASUS RT-N66U router which serves as my LAN’s DHCP Server. Setting it up to utilize Cloudflare’s DNS Server address of 1.1.1.1 was easily accomplished. However, the setup of the IPV6 setting is a problem in that I need to select the connection type from the displayed choices of Native (Automatically assigned by my ISP, Charter/Spectrum), Static IPV6, Passthrough, FLETS’s IPV6 service, Tunnel 6to4, Tunnel 6in4, and 6rd.

Which of those is the proper choice?

If you visit https://canhazip.com/ what IP address do you get an IPv6 address back?

Or if you visit https://whatismyipaddress.com/ds-check does it return both an IPv4 address and an IPv6 address?

Thank you for your interest.

IPv6: 2600:6c51:7b80:34b2:840c:6964:88f7:a53d
IPv4: 71.95.56.87

Those are due to my use of my ISP’s DNS servers. That was a few minutes ago and are no longer the addresses assigned for my use.

I’m puzzled as my question is with regard to how to setup the IPV6 settings in my router to utilize IPV6 with Cloudflare’s DNS servers. I know the addresses to use. I really just need to know what type of connection is the right one for me.

I was trying to determine if you had IPv6 addresses at all, not every ISP provides them. Since you appear to have them and they are from your ISP, I would assume then that Native would be the correct choice.

I understand. IPV6 was a long time coming to my neighborhood from Charter/Spectrum.

Native is the default selection and just uses the dynamic addresses and settings assigned by my ISP and can’t be changed.

I’ll continue my search for the answer.

Thanks.

The answer appears to be, 6rd, as it works.
