If you are running Mac OS X, you will notice that whenever you visit an online site, the IP will get cached for a set period of time. This is just how the system is programmed to function. When moving domain names from one server to another; it can be a hassle to have the IP’s cached. This also occurs when you go through with a domain name server lookup, because the IP will get cached indefinitely. The DNS cache is a Mac file whose responsibility is to convert host names to IP addresses. If your domain name server cache is corrupted or has errors, it can cause some many problems. The issue usually affects server administrators and developers.
Steps to Flush DNS Cache in Mac OS X
To begin, you need to open the Terminal application. Start by opening a new Finder Window. You should now redirect to Applications/Utilities/Terminal, and open the application. Depending on the version of Mac OS X you are running, the command will vary. For those using version 10.5, your command is “dscacheutil –flushcache”. For those using version 10.4, your command is lookupd –flushcache. Version 10.5 is Leopard and Version 10.4 is Tiger, for those who prefer it that way.
What Happens After the DNS Cache is Flushed?
When the process is done, your domain name server cache will be fully cleared. If you had errors with resoling host names and IP addresses, this should have fixed the issue. Many people who use Mac OS X have noted numerous errors with the DNS cache, so please note that flushing the DNS is the only simple solution out there. As of now, there isn’t a special application of system that does it automatically. If you receive errors or pop-ups, you will have to complete the command manually by using the Terminal application. If you would like to do the same for your Windows powered system, you can use the command line “ipconfig /flushdns”. In the Windows OS, DNS cache errors are very nominal when compared to Mac OS X powered systems.
