I don't really see the issue. It changes nothing from the DNS client's perspective.

- toast0 7y agoFrom the DNS client's perspective, there is a positive and a negative. Positive: since the server with an alias record actually returns an A/AAAA, a client doesn't have to contact any more servers to get the results. Negative: the servers for the CNAME target may be faster, relevant if the name is used beyond the A/AAAA TTL but sooner than the TTL would be set for a CNAME); or the servers for the target may be providing much finer targeting than is possibly by proxying.
