I am unsure what the following sentence in bold means
If you are using only the hostname (without the domain information) to connect to a server, the application you're using may not be able to resolve the hostname. This can happen if either the DNS suffix search order in your computer's TCP/IP properties is incorrect, or the DNS table is corrupted. In these cases, entering the host's FQDN will allow DNS to locate the server. --
I know that FQDN means the following in www.mySite.com
- www is the 1st domain
- mySite is the 2nd level domain
- com is the 3rd level domain
I know that DNS stands for Domain Name server. It seems that DNS is the collection of FQDN.
What does the sentence in bold mean exactly?
