Unable to open socket to 1.1.1.1 port 53 from a Worker using the TCP sockets API

While attempting to read DNS packets after sending a TCP DNS query to Cloudflare’s 1.1.1.1 endpoint over port 53, I get an error stating “Stream was cancelled”. I’m establishing the TCP socket using the “cloudflare:sockets” package.

I know there’s the segment in the documentation that mentions outbound TCP sockets to Cloudflare’s IP ranges being temporarily disallowed, but don’t see the DNS IP addresses listed in the IP ranges document that’s linked. Are the DNS IP addresses included in the blocklist for outbound connections? And if so, is there a timeline for when outbound sockets to Cloudflare IP addresses will be re-enabled?
