Domain Name System (DNS) is a database system that translates a computer's domain name into an IP address. It is easier for us to remember the domain name than the IP address for that site. Therefore this job of translating the site name to IP address is done by the DNS database.
Whenever you enter the site name like www.sitename.com, the browser will go to the site but it will look for a number like this 192.128.18.9. It is faster to look for the number. But every time your browser will look for the DNS address on the net then take you to that site. This searching for the DNS address will take longer time for the site to load. Therefore your computer saves this information in the DNS cache and it will search for this information when you enter a site name which will improve your browsing speed.
You can increase this cache size in Windows to acquire more addresses .You have to add some registry entries for this tip. Here is how
--- Type regedit in the Run dialog box to go to the registry.
---Then look for the key
--- In the right pane look for the following entries. If they are not present then create them by right clicking in the blank area in the right pane and selecting New --> DWORD value.
Now create these entries and change their values by double clicking on them and enter the given values.
CacheHashTableBucketSize and give a value of 00000001
CacheHashTableSize with a value of 00000180
MaxCacheEntryTtlLimit give the value 0000fa00
MaxSOACacheEntryTtlLimit with the value 0000012d
You are done. Now restart your system for the changes to take effect.
