This guide provides detailed steps for setting up DNS records, configuring a DNS tunneling server and client, and setting up a browser for secure proxy connections.

Why iodine?

Bypassing Network Restrictions: iodine excels in environments with strict network restrictions. It utilizes DNS queries, which are typically allowed through firewalls, to tunnel data where traditional methods like VPNs might be blocked.
Efficient for Limited Bandwidth: Ideal for situations with bandwidth limitations, iodine requires less bandwidth compared to standard VPNs, making it a practical choice for networks with restricted data flow.
Customizability and Open Source: As an open-source tool, iodine offers extensive customization options. Users with specific technical needs or those interested in a hands-on approach to network tunneling can tailor iodine to their requirements.
