DNS Accelerator
What is the DNS Accelerator?
The DNS Accelerator speeds up conversion of textual host names on the Internet into numerical IP addresses. Therefore, with the DNS Accelerator you browse faster and without unnecessary delays.
How does the DNS Accelerator work?
Normally, when your computer needs to resolve an Internet host name into its numerical address, it contacts your ISP's DNS server. That DNS server sends a query to another DNS server which is responsible for the domain where the host in question belongs. After the reply for that query is received, it is passed back to your PC. Clearly, this procedure takes some time, and in extreme cases can take many seconds.
The DNS Accelerator records "host name to IP address" mapping locally on your computer, stored in the Windows Hosts file, and the next time host resolution is required, the answer is available instantly!
Why are periodic updates essential?
