DNS Setting To Improve Internet Connection

Mostly people expect a fast response when they browse the internet, but it doesn’t always run as mostly people expect. Typically there are many factors that contribute a slow internet connection such as: a bad line from the customer premises to the nearest central office of the service provider, Central office problems, buggy software, and mostly due to the Web farm servers you browse to at the other end of the connection. So how do you speed up internet connection?Do you want to learn more? Visit DNS settings on a computer.

Generally when you sign-up the internet connection, there should be such kind of a service level agreement at least we know the bandwidth rate they provide the services to the subscriber. If you use traditional dial-up connection the maximum bandwidth will be 56Kbps. You cannot speed up internet connection exceeding the architecture limitation. DOCSIS 3.0 Cable architecture probably can provide you faster speed up to 300 Mbps – but depends on the infrastructure the ISPs have built.

Definitely it is beyond our control when the bottom lines of the problems come from the ISP, the central office equipment, and slow web servers. But basically you can tweak the computers to get them in high performance in browsing the internet. The following guidelines will help you manipulate the computers to speed up internet connection.

How to tweak DNS setting to speed up internet connection

When you type in the hostnames in the browser such as cisco.com, the DNS resolver needs to translate it into the corresponding IP address such as 55.125.102.113. DNS servers provide that name resolution automatically and behind the scenes as you surf the Web.

Editing Host File

A very simple way to speed up internet connection regarding the DNS setting is by editing the computer local hosts file. It takes time to send your request to a DNS server, have the server look up the proper IP address to resolve the name, and then send the IP address back to your PC. You can eliminate that delay by creating or editing a local HOSTS file on your own PC that contains hostnames and their corresponding IP addresses.

Windows will first lookup the entry in the HOSTS file to see if there’s an entry for the hostname, and, if it finds it, it will resolve the address itself. That way, you won’t have to go out to a DNS server and wait for the response before visiting a web site. You can edit the HOSTS file with the notepad editor and you can create lists of most frequent web sites you visit.

You’ll find an existing HOSTS file in C:\System32\Drivers\Etc\HOSTS. Open it in Notepad and enter the IP addresses and hostnames of your commonly visited web sites with the following format:

65.301.110.37 sysneta.com #example of the entry

67.101.200.107 computer-network.net

Each entry in the file should be on one line. The IP address should be in the first column and the corresponding hostname in the next column. At least one space should separate the two columns. You can add comments to the file by preceding the line with a hash (#),

Adjust the Computer DNS Caching Settings

You can also adjust the DNS Caching setting to help speed up internet connection. When you visit a site, Windows puts the DNS information into a local DNS cache on the computers. When you browse a website, your Computer first looks in its local DNS cache, called the resolve cache, to see whether the DNS information

is already in there. If it finds the information locally, it doesn’t have to query a remote DNS server to find IP information. The cache is made up of recently queried names and entries taken from your HOSTS file.The cache contains both negative and positive entries that we can hack to help speed up internet connection.
