  • What is DNS?

    Domain Name System (aka DNS) is the system designed in the early days of the Internet, created to resolve human-readable domain names (eg. dnslog.com) into readable IP addresses like: 185.56.25.47. DNS also is useful to provide public information about the DNS records, like email servers, cnames, txt and other type of DNS records.

  • What's My DNS?

    When your DNS records are edited/modified in some way, it may take up to 72 hours for all the global DNS servers to notice that change. That's what is called DNS Propagation time or DNS resolution time. You can run our DNS report if you have cached DNS so we can detect domain dns lookup to check if your domain IP changed or not.

    Depending on the ISPs, TTLs and DNS servers it may take from some hours, to 72 hours max. If your domain or web page doesn't resolve after 72 hours, then it's a configuration error for sure. At dnslog.com you will find our DNS propagation test to find out how your domain names are propagation across the world.
