What is a DNS lookup?
DNS Lookup shows public information (DNS records) for a given domain including A records, email (MX) records, CNAME records, text (TXT) records and nameserver (NS) records. Our lookup suppots both IPv4, IPv6, and domain name input.
How does it work?
Our DNS lookup checks on the status of world wide DNS resolutions using top rank DNS resolvers such at 1.1.1.1 (Cloudflare) and 8.8.8.8 (Google). It relies on our proprietary PHP8 IP & DNS utility library to make requests.
