School Internet filters work by restricting access to certain websites and online content that may be deemed inappropriate or distracting for students. These filters use a variety of techniques to block access to specific sites or content, including:

URL Filtering: This technique blocks access to websites based on their web address (URL). The filter maintains a list of banned URLs, and any website on that list will be blocked.

Keyword Filtering: This technique blocks access to websites based on certain keywords that appear in the website's content. The filter scans the website for specific words and phrases and blocks access if they match the banned keywords.

Content Analysis: This technique blocks access to websites based on their content. The filter uses algorithms to analyze the content of a website and block access if it contains inappropriate or distracting material.

IP Filtering: This technique blocks access to websites based on their IP address. The filter maintains a list of banned IP addresses, and any website hosted on a banned IP address will be blocked.

DNS Filtering: This technique blocks access to websites by redirecting the domain name system (DNS) lookup to a different IP address. The filter maintains a list of banned domain names, and any website associated with a banned domain name will be redirected to a different IP address or blocked altogether.

Overall, school Internet filters are designed to protect students from accessing inappropriate or distracting content online while allowing access to educational resources. However, they can also be overly restrictive at times, blocking access to legitimate educational content or websites.
