Key Takeaways
- A study examined Indian internet providers website blocking practices, revealing significant variations across ISPs.
- The research identified methods like DNS manipulation and HTTP filtering used to restrict website access.
- Only about 27% of websites tested were consistently blocked by all providers, leading to inconsistent user experiences.
- Some websites were blocked without legal justification while others remained inaccessible even after restrictions ceased.
- The study highlighted that Indian internet providers website blocking practices impact access based on the user’s provider, reflecting uneven enforcement of regulations.
A study examined Indian internet providers website blocking practices across major internet service providers. Researchers tested how different ISPs in India restrict access to websites. The analysis focused on identifying differences in blocking methods and enforcement. Results showed that website access varies depending on the internet provider used by a customer.
Researchers compiled a large dataset of websites that might be restricted in India. The list included domains referenced in government orders, court rulings, and reports from internet monitoring groups. The dataset contained more than 4,000 websites. Tests were performed using connections from several leading Indian ISPs.
Methods Used in Indian Internet Providers Website Blocking
The study identified several techniques used for Indian internet providers website blocking. One method involved Domain Name System manipulation. DNS blocking prevents a domain name from resolving to its correct internet address. Users attempting to access the site receive an error or redirection.
Another technique involved HTTP filtering. In this method, internet providers intercept traffic requests and block specific websites before the page loads. Researchers also observed filtering based on Server Name Indication in encrypted traffic. This technique allows ISPs to block websites even when HTTPS encryption is used.
Different ISPs applied different combinations of these methods. The implementation varied widely across providers.
Differences Found in Indian Internet Providers Website Blocking Lists
Researchers compared blocklists used by multiple providers. Only about 27 percent of the tested websites were blocked by every ISP. Many domains were blocked by some networks but remained accessible on others.
One provider blocked more than 3,700 websites in the dataset. Another provider blocked far fewer sites. These differences created inconsistent access for users across the country.
Some websites were blocked even though they were not listed in known legal orders. In other cases, websites remained blocked after restrictions had been lifted. These findings showed uneven enforcement of blocking instructions.
Indian law allows website blocking under provisions of the Information Technology Act. Government agencies and courts can issue orders requiring access restrictions. However, regulations do not mandate a single technical method for enforcement.
The study concluded that Indian internet providers website blocking practices result in varying internet access depending on the service provider used by each user.
