There are many reasons why someone might need to learn how to block a website. It could be a parent blocking one from their child or a company’s IT department blocking certain websites from their employees. No matter why one chooses to do this there are different ways to go about it.

Blocking A Website Using Windows OS

To block a website using a Windows OS the first step is to log in to the computer as an administrator and run the Notepad application that comes standard on all Windows-based PCs. Depending on the computer’s security settings it may be necessary to enter a password to complete this step. The next step is to click on” File,” click on “open,” and open the host files. It is then necessary to scroll down, press Enter and type the numbers and then enter the website to be blocked.

This method can be used to block an unlimited number of websites.

How To Block A Website On Firefox

Firefox has built-in parental controls that can be used to block any website. They also offer extensions that can be downloaded to any computer and used to block websites one would prefer to avoid access to. These extensions work in Firefox only, meaning sites blocked from the Firefox browser can be viewed on any other Internet browser. This means it is not a full-proof way to block sites and parents should be aware of this if they are trying to block sites from their children.

There are three types of extensions offered by Firefox that can be used in different ways to block websites. Those are ProCon, LeechBlock and FoxFilter. ProCon has limited ability in blocking sites because it can only be used to prevent users from accidentally visiting an undesirable site. It is considered a blunt website filter because it still allows users to access some sites they may find questionable.

LeechBlock is strictly for parents who want to control how long their child can view a particular website. It cannot do anything to block any website completely. All it does is cut off access to the site after a pre-determined period of time that can be set by parents.

FoxFilter is the extension that parents love the most when it comes to locking their child’s access to websites. It is effective at blocking the pornographic websites that many children in the throes of puberty actively seek out. It can also be used to block other types of websites parents don’t want their children seeing.

How To Block A Website In Internet Explorer

Internet Explorer has long been the most widely used browser. Blocking a website using Internet Explorer is easy to do. The first step is to click on Tools, followed by Internet Options. Then it is necessary to click on the Privacy tab and within that window click on Sites. At this point, it becomes as simple as typing in the web address that needs to be blocked and clicking OK. The only limitation to this is that it can only be used to block one website at a time. To block another website using this method on the same computer means that the website that was blocked previously must then be removed.

One way to block websites on Internet Explorer 9 is to click on the icon called gear. The next step is to click on Internet options and then the content tab. The Content Advisor must then be enabled. The next step after that is to click on the tab that says approved sites. The user then simply has to type in the URLs of the websites that they want to block their children from seeing, The final step is to then press the never button. This tells the browser that users are never allowed to access those particular websites on the computer.

How To Block A Website Using OpenDNS

Another way to block a website is to use an online OpenDNS program (that is not software.) The OpenDNS service is free and gives users the ability to block websites. With more than 50 category filters it is an easy way to block undesirable websites. Blocking certain websites by using a domain basis is possible. The only limitation to using this domain basis is that it won’t block and because OpenDNS is associated with them. Entire domains can be blocked by simply enabling the “typo correction” feature of the service. A web proxy can also be used to block access to certain websites.

How To Block A Website On Opera 11

Opera 11 is a lesser-known web browser that also gives users the ability to block websites. The built-in website blocking feature can accommodate an unlimited number of sites. The first step is to click on the Opera Menu, then click on settings and then click on preferences. It is then necessary to click on advanced, followed by content, followed by blocked content. At this point all the user has to do is enter the URL for any website they wish to block.

How To Block A Website On Chrome

Google Chrome is a web browser that is gaining in popularity every day among Internet users. In order to block websites in Google Chrome users have to download a free extension called SiteBlock. Once it has been installed users simply click on settings, then click on tools, then click on extensions and then click on SIteBlock. Once a user is in the SiteBlock panel they are free to block any website.

How To Block A Website On iPhone

Though many users don’t realize this it is actually possible to block websites from being viewed on an iPhone or iPad. On the phone or tablet the first step is to click on setting, then general, then restrictions. The next step is to turn off Safari, which will make it impossible to view websites through the Safari browser found on many iPhones and iPads. An additional step that can be taken is to disable the phone or tablet from being able to install new software. This will prevent the person using the device from simply downloading a web browser other than Safari in order to get around the blocked website setting.

If a parent is trying to set up their child’s iPhone or iPad to restrict them from certain websites but allow them to view others, the blocking process is different. In this case, parents can simply configure the device’s WifI DNS so that questionable websites are blocked while access to other websites is permitted. The other option is for a parent to download a browser other than Safari to their child’s iPhone or iPad because then they will have access to parental controls through those alternate browsers.

There is a third-party web browser called the K9 Web Protector that can also be used by parents to block websites they don’t want their children to see. This web browser works much the same way Safari does but it comes with parental controls that allow the blocking of undesirable websites. There is a version of the K9 Web Protector for iPhones and iPads as well as one for Android phones and tablets.

Blocking Websites On Android Devices Using K9 Web Protector

The K9 Web Protector can be put onto a mobile device using a method that prevents children from being able to access and disable it. If a child (or any other user) tries to access a website that is in the K9 Web Protector Database they will not be allowed to view it. The websites in the database include pornographic websites, gambling websites, and those that promote profanity and/or hate speech.

Blocking Websites In Search Results For Google

Another way to block select websites so that they don’t come up in the results of a Google search is to download the Personal Blocklist” extension. Once this extension has been installed it allows parents to prevent specific websites from showing up in search results.

A user can then type a query into Google and view the results. Once they are doing so they can see the results of the search that came from sites the parent doesn’t want to be accessed. At the end of each URL that shows up in search results users will find the word “Block.” All they have to do is click on the hyperlink and that particular website will disappear from the screen. This can be done for an unlimited amount of websites and is an effective way for parents to eliminate their children’s access to websites they don’t want them seeing or even knowing about.

Going forward, any site that the user blocks will not show up in a Google search at any time. It is possible for parents to keep track of all the websites that they have blocked from showing up in search results. A list of the blocked websites can always be accessed by clicking on the red icon that will appear in the address bar once this extension has been installed.

How To Block A Website’s IP Address

If a user wants to block a website’s IP address there are certain steps they must take. To block the Facebook website through its IP addresses the first step is to access the global configuration mode. The second step is to put together what is called an Extended Access Control List. ACL statements are then created that will serve to block the websites. For each website, a user is trying to block they must type in a separate statement.

To block Youtube all of the ISPs assigned to Youtube must be audited. By the time this is done a list of ISP numbers associated with Youtube will have been created. Whois is a website that can be used to find all of the ISPs assigned to a particular website. Until every one of them is audited it is still possible to access these sites.

Parents who want to block their children from being able to access must do so using their computer’s firewall. The reason for this is that this is a way to block the site without relying on the ISP numbers to do so, as those numbers can be changed.


When it comes to how to block websites without the use of software all of the ways mentioned above are viable options, though none of them is as secure as using the software. For those who don’t want to use software to block websites from being accessed on their computer, each of the above methods can be put into place. It is important for parents to be able to block websites they don’t want their children reading, which is why there are so many ways to do so.

Blocking certain websites is one task that many companies’ IT departments spend a considerable amount of effort on. Many companies block their employees from being able to access social media websites on work computers so that they do not waste the day using those sites instead of getting their work done. Other companies block access to any website whatsoever so that their employees don’t need to be able to do their jobs effectively.
