Coming Soon: Open DNS

We are always on the lookout for solutions to your technical troubles. Internet security, phishing and content filtering are often subjects which we are asked about and so we have been trialing a product which will be able to do all of this for you. Soon we will be able to provide all of our customers with a service called Open DNS which is designed to provide an extra layer of security to your network.

First things first:

What is DNS?

Domain Name Services (DNS) act as the internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses. Almost anything you do on the internet will be facilitated by DNS.

Who provides DNS?

It is most likely that your DNS is provided by your internet service provider (ISP). ISPs provide DNS as a standard but you do not have to use your ISP’s DNS and in fact there are a number of benefits from using a third party DNS.


What are the benefits of OpenDNS?

Possible speed improvements

It is not true for everyone but many users find that using third-party DNS servers are quicker than using the ISP’s. However, just as with internet speeds, DNS speeds are effected by where you are, who your provider is etc.

Reliability improvements

Reliability improvements are also dependant on the service your current IPS is providing. If your current ISP is unreliable because their DNS servers are not fast/ stable then you may experience frequent downtime and struggle to load some webpages. Switching to OpenDNS could mean that the reliability increases as the service uses self-healing to ensure that the system is protected against tremendous disruption.

Typo correction

This is a small bonus but a very handy one. If you type a website’s domain name into your browser for a popular website and miss a letter (e.g. then the service will recognise it, correct it and take you to the page you are looking for automatically.

Web filtering

The ability to filter web content is becoming increasingly important for businesses. Not only can you deny access to any website which is deemed Not Suitable for Work but you can stop access to any sites which may be harmful and

Phishing protection

This is in a similar frame to web filtering in that if a site is identified as a phishing site then it will come up with an error saying that the site is blocked on your network. OpenDNS uses data from a community site call Phishtank to determine whether the site is safe.
