About your IP

Hosts

Protocols

You are using https. You can also reach this via http: http://ipv6.robtex.com/html

No DNS or TLS needed: http://46.255.120.53/ip and http://[2a00:9c00:120::53]/ip hit the same anycast service by IP literal — handy when your resolver or clock is broken.

Related: which resolver am I using?

The DNS-based siblings echo your resolver instead of your client IP: dig +short dnsip.robtex.com (or dnsipv4 / dnsipv6), and dig txt dnsip.robtex.com for resolver PTR/ASN/EDNS details.
