This site will provide you with a DNS report for your domain. A very large percentage of domains have DNS problems; this site will help you find those problems and fix them. Also, the "Mail Test" tool will help find mail delivery problems for your domain. This site is a sister site to www.DNSstuff.com, which has many other DNS and networking tools.
We also have forums, where you can ask questions and find out more information about the DNS reports.
For the DNS Report, all you need to do is enter the domain name you wish to have the report made for. You need to enter the domain name ("example.com"), not the host name ("www.example.com"). Note that IP addresses don't work here. Also, the DNS report may connect to the mail server(s) for your domain; if it does, the mail server(s) will have access to your IP in their logs (to help prevent abuse). If you want the DNS report to query a specific DNS server (for example, if you are about to switch to new DNS servers, and want to test them before going live), you can do a DNS report on your domain, and then you can add "&server=ns1.example.com" to the "Location:" line in your browser, and the DNS report will query the DNS server you specify (ns1.example.com in this case). To use the Mail Test tool, just enter a domain name ("example.com") or an E-mail address ("user@example.com"). If you enter a domain, the Mail Test tool will show which server(s) are used for mail delivery for the domain, and what order they should be used in. If you enter an E-mail address, the Mail Test tool will also try connecting to those servers. There is no cost for the DNS report. If you find these tools are useful, we also use and recommend dnsmadeeasy.com for DNS hosting, and GoDaddy for domain registration. Also, if you need anti-spam or anti-virus software for your mail server, please consider looking at the excellent Declude products. Or if you want your email filtered for you, please consider Mailprotector. Thanks! http://www.dnsreport.com
