031 | Proxy Servers in Action: 3proxy — A Compact and Multifunctional Proxy Server 🤏⚙️

In our exploration of proxy servers, we’ve already looked at giants like Nginx and HAProxy, as well as the versatile SOCKS-focused Dante. Today, we turn our attention to 3proxy — a surprisingly compact yet incredibly multifunctional solution that could become your Swiss army knife in the world of proxying.


What is 3proxy?

3proxy is free, open-source software that, despite its small footprint (hence the “3”), is one of the most versatile proxy servers available. It is designed to run on various operating systems including Windows, Linux, macOS, and BSD. Its main strength is its ability to act as a proxy for a wide range of network protocols, often not supported in more specialized solutions.

Now that you know about the different types of DNS records, let’s figure out how to configure them and, just as importantly, how to ensure everything is working correctly. Proper DNS setup is a key step to your website’s stable operation and effective email delivery.

Where and How to Configure DNS Records?

DNS record configuration is typically done in the control panel of your domain registrar (where you purchased the domain) or through the interface of a service you use to manage DNS (e.g., Cloudflare, if you use it).

Continuing the topic of DNS, in addition to the basic A and MX records, there are three other critically important records that are responsible for the security of your mail and its deliverability — that is, ensuring your emails don’t end up in spam. These are SPF, DKIM, and DMARC. They act as unique digital seals and verification rules for your correspondence, confirming its authenticity.

We’ve already discussed how to get your own domain and reviewed the available options for building and hosting a website and email. Now it’s time to dive into what ties all these elements together — the Domain Name System (DNS). Think of DNS as the internet’s giant phone book: when you type an address like yourbusiness.com into your browser, DNS servers help translate that name into the corresponding IP address (e.g., 192.0.2.1) so your browser knows where to connect. Without proper DNS configuration, your website won’t be accessible, and your emails won’t be delivered.
