Zero Trust 1.1.1.1

Is it intentional that the DNS entries for 1.1.1.1 and 1.0.0.1 are the same?
[~]$ dig -x 1.1.1.1 +short
1dot1dot1dot1.Cloudflare-dns.com.
[~]$ dig -x 1.0.0.1 +short
1dot1dot1dot1.Cloudflare-dns.com.

Yes it is. Under 1dot1dot1dot1.Cloudflare-dns.com there are all the 4 IPs for the 1.1.1.1 DNS resolver.

Ah, thanks for confirming. I guess I was just expecting to see something like 1dot0dot0dot1.Cloudflare-dns.com for the ipv4 lookup.
