DNS setup and resolution is important for your on-going business. Without properly configured DNS, your customers cannot find you online. It’s a pretty common story: You setup a new server and configure the DNS and you can see it on your network, but can anyone else get to your server? Everything isn’t setup and running until you check DNS resolution with an external 3rd party.
Fortunately, MxToolbox provides free tools that allow you to check your DNS resolution externally, so you can verify what your customers see.
Our DNS Lookup tool will return all the authoritative A records for a domain. This is useful to ensure basic DNS configuration.
Our SuperTool contains a number of useful DNS lookups. Most often our users check on DNS records for mail like MX, SPF, DMARC, and DKIM. However, we support the most common DNS lookups, including A, AAAA (for IPv6), PTR, SOA, TXT, LOC and others.
SuperTool also includes a lookup (DNS:) for all the name servers authoritative to your domain so you can see them all at-a-glance. This lookup includes an analysis of the name server configuration compared to relevant RFCs.
