Content filtering (also known as information filtering) is the use of a program to screen and exclude from access or availability web pages or e-mail that is deemed objectionable. Content filtering is used by corporations as part of internet firewall computers and also by home computer owners, especially by parents to screen the content their children have access to from a computer.
How Content Filtering works?
Someone on your network begins navigating the internet with their computer.
They enter the name of a website (e.g. www.vpscity.co.nz) into their internet browser.
The browser makes a DNS request for the IP address of the machine that serves up this website.
The DNS request is received by an DNS server.
DNS server identifies the DNS request by looking where it came from.
DNS server looks up the matching filtering and security settings.
If the settings indicate that the website is allowed, DNS server returns the IP address for that website (e.g. 22.214.171.124) and the browser goes there.
If the settings indicate that the website is blocked, DNS server returns the IP address of an OpenDNS server that serves a block page to the browser.

An internet filter can block all these places. If you are aware of any content that your children ought not to visit, you can specifically block the content.
Specifically, in schools and colleges or any other educational institute, it is very important to keep children away from inappropriate content. This is achieved by internet filtering. Applying internet filtering software ensures that children are viewing and visiting age appropriate websites and content only. Blocking websites that are not appropriate for children is one of the biggest advantages of internet filtering.

By installing internet filters, employers can expect an increase in employee productivity.
Content Filtering Benefits
VpsCity Content Filtering lets you manage the internet experience on and off your network with acceptable use or compliance policies, putting you in control.
The easy-to-use, cloud-delivered administration console enables you to quickly set up, manage, and test different acceptable use policies per network, group, user, device or IP address, giving you greater control of your organisation’s internet usage.
Our Filtering enables you to customise our category-based filtering to meet each network’s specific needs, particularly to help you meet compliance requirements. Quickly create exceptions to allow or block specific domains, regardless of whether it is in a category that is allowed or blocked.
Allow or Block Specific Domains
Allows you to create allow and block lists for specific domains. Whitelisting domains ensures that you can always access particular sites, even if it is in a category that is being blocked. Blacklists operate in the opposite fashion by ensuring that a site on the blacklist is never accessible to your users.
Block Page Bypass
Block Page Bypass lets you grant special permission to circumvent filtering settings without the use of any software or appliance. This feature enables you to assign individual users, such as your marketing managers, the ability to access specific filtering categories, such as social networking, or individual domains that are normally blocked on your network.
