Adblocker versus denied hosts list?


: This article presents a comparison between adblockers and denied hosts lists as solutions for blocking ads on websites. It discusses the effectiveness, advantages, and disadvantages of both methods.



1. Introduction
Ads are an essential source of revenue for many websites. However, they can also be annoying and intrusive, affecting the user experience. Two common methods to block ads on websites are adblockers and denied hosts lists. This article compares these two methods to help you decide which one is best suited for your needs.

2. Adblockers
Adblockers are software programs that block advertisements from appearing on web pages. They can be installed as browser extensions or standalone applications, depending on the type of adblocker. Adblockers work by filtering out ads based on their source and blocking requests for them to load on a web page. There are many types of adblockers available, including open-source and commercial options.

3. Denied hosts lists
A denied hosts list is a list of IP addresses that are not allowed to access a website. It can be used to block ads by preventing the ad server from loading on the web page. Denied hosts lists can be created manually or generated automatically using software tools. They work by redirecting requests for blocked IP addresses to a blank page, effectively preventing them from loading.

4. Effectiveness
Adblockers are generally more effective at blocking ads than denied hosts lists. Adblockers have advanced filtering capabilities and can block ads from multiple sources. Denied hosts lists, on the other hand, only work if the ad server’s IP address is included in the list. However, ad servers can change their IP addresses frequently, rendering a denied hosts list ineffective.

5. Advantages of Adblockers
– Blocks ads from multiple sources
– Can block pop-ups and other intrusive ads
– Can improve website load times by reducing the number of requests made to ad servers
– Available as browser extensions, which makes them easy to install and use

6. Disadvantages of Adblockers
– Can break some websites’ functionality
– May prevent some features from working, such as comment sections or social sharing buttons
– Some websites may block access if an adblocker is detected
– Commercial adblockers may require payment for additional features

7. Advantages of Denied Hosts Lists
– Can be used to block ads and other unwanted content
– Can improve website security by blocking malicious IP addresses
– Does not affect website functionality or break any features
– No need to install additional software, as it can be configured in the web server’s configuration file.

8. Disadvantages of Denied Hosts Lists
– Requires technical knowledge to create and maintain
– May require regular updates to keep up with changing ad server IP addresses
– Can affect website performance if too many IP addresses are blocked
– May not work effectively on websites that use dynamic IP addresses for ads.



Both adblockers and denied hosts lists can be effective methods of blocking ads on websites. However, adblockers are generally more user-friendly and provide a higher level of effectiveness. Denied hosts lists require technical knowledge to set up and maintain and may not work effectively in all situations. Ultimately, the choice between these two methods depends on your technical expertise, the specific needs of the website you wish to use them on
