Check DNS Consistency across all Name Servers


This free online tool from SolveDNS allows you to check the consistency of A (IP address), AAAA (IPv6 address), MX (mail exchange), NS (name server) and TXT (used for SPF) DNS records across all of the name servers of the domain name. The tool will report an error if any of the name servers have different records as compared to the other name servers of your website.

Having the same DNS records across all of the name servers of a domain name is very important to ensure consistency across users around the world. Different recursors (your ISP's DNS server) might use different name servers an if the DNS records are different, your visitors might experience an unwanted experience including your website being down.

Having at least 2 name servers and having your DNS records consistent across all of the name servers is crucial to proper functioning of your website. Use this tool as often as you please to ensure consistency of your DNS records. If you are looking for consistency across different parts of the world, use the DNS propagation tool on this page.
