MSNBot Reverse DNS Test Fails Requirements

A year ago, Microsoft promised to enable Webmasters a method of . Way too often, rogue spiders mask themselves as official spiders from Google, Yahoo, Live Search or Ask.com.

Why You Should Always Have A Web Hosting Exit Strategy

You can test that the website is working correctly by changing the hosts file in the operating system so that it links the new IP to the domain name. Very helpful to test a site before DNS propagation. And since you are waiting for the DNS to propagate you can at least do something useful in the meantime. You can check if the nameservers have been set correctly at web services such as DNS stuff. A traceroute to the domain can also provide the information if the DNS has propagated already.Live chat or calling is often the faster option to resolve a situation. It is a good idea to have the [more...]

DNS usually takes from 12-24 hours to propagate throughtout the internet. Of course sometimes it takes up to 48 hours.

Check DNS Reverse Lookups (check-dns) | OpenNMS Patterns and Scripts

Issue OpenNMS stores DNS reverse lookups for the IP addresses it discovers (iphostname column of the ipInterface table). It appears that OpenNMS only performs the DNS reverse lookup once and stores the result. Therefore, OpenNMS may never be aware of a DNS change. The DNS reverse lookup is visible in the OpenNMS web interface on the node page as “IP Host Name”. An outdated entry here can cause confusion. A way is needed to keep this information up to date. More serious problems can occur when OpenNMS uses DNS reverse lookups for node labels (see How are node labels determined? for [more...]
