I’ve found one edge case where blocking AAAA records fixes something in order to force it to A addresses. Netflix I use a Hurricane Electric tunnel for my IPv6. Works like a charm for every other site I use. But Netflix rejects connections because it thinks it’s on a VPN. So, filtering the quad A makes it appear it isn’t IPv6 enabled, so it connects over 4. Works like a champ. Eric
