I was reading about proposed changes to RFC 6724 which determines the priority for IP address selection. In the original RFC 6724, IPv4 addresses are given preference to IPv6 Unique Local Addresses (ULA). The proposed changes would reverse that. However, in testing with ping, I see ULA is preferred, except for the computer being used for testing from. That is when a computer is pinging itself. Why the difference? Why is the proposed priority used when pinging a different device, but not the same device? Also, if I use the FQDN, instead of just the host name, then ULA is used. WTF??? I'm using the DNS resolver in pfSense. The host command returns both IPv4 and ULA addresses for both host name and FQDN Original - https://datatracker.ietf.org/doc/html/rfc6724 Proposed - https://datatracker.ietf.org/doc/draft-ietf-6man-rfc6724-update/ Running openSUSE 15.5 & KDE.
