I have a mail server for which I need to create the AAAA DNS record and update the SPF record to include its IPv6 address.
ifconfig command shows a Scope:Link IPv6 address and a Scope:Global IPv6 address. Which one should I put in the AAAA and SPF records?
The Scope:Global is a /128 address and the scope:Link a /64.
The Scope:Link address is a FE80 address which means none routable. Does it mean I have to put the Scope:Global address?
