Help Center Troubleshooting Problems with Ad Serving
How do I troubleshoot my ISP's nameservers?
The DNS servers of your local Internet service provider can block access to our ad servers or they do not resolve our domain name to the correct IP addresses.What is a Name Server?
Nameservers are used by ISPs (eg: Comcast, Verizon, Time Warner, AT&T, AOL, etc.) to map hostnames (eg: www.adspeed.com) to IP addresses (eg: 127.0.0.1). If a nameserver server has problems, users of these servers will experience connection problems to any/many websites. In Firefox, the error message is normally "Server Not Found". When this happens, visitors using another working nameserver would be able to access the websites normally.Problem Identification
You can access a page via the hostname and the same page via the direct IP address. If you can access both files then your ISP's DNS servers are working properly. If you can see only the page via the direct IP address then you are having a DNS problem. Please continue with the verification process below.Verification
To verify that your ISP nameservers are causing accessibility problems, you could ping our servers or perform a nameserver lookup on g.adspeed.net. Instructions:- Windows: Click on Start/Run and type
cmd - Mac OS: Open Terminal application from menu Finder/Utilities/Terminal
- When the command-line window appears, type
ping g.adspeed.net - To perform a lookup of hostname
nslookup g.adspeed.net - To perform a trace route to our adserver
traceroute g.adspeed.net - Open a technical support ticket and send us the results for analysis
Solution
If the ping/nslookup results contain any error message or show some packet loss, you should contact your ISP and ask if they have or know of any issue with their nameservers or network. Or you can try to use another DNS server, like Google DNS or OpenDNSOther Articles in Problems with Ad Serving
