Have you ever connected to public Wi-Fi at an airport or coffee shop and worried about strangers spying on what you‘re browsing or sending online? Or tried accessing a website or service that‘s blocked in your country?
A Virtual Private Network (VPN) solves these issues and more by encrypting your internet traffic and routing it through remote servers for security and anonymity. But what goes on behind the scenes of a VPN?
VPN servers are the backbone of any VPN service. They act as middlemen that take your web traffic, scramble it so no one can see what you‘re doing, and provide entry points into blocked websites and networks across the globe.
In this comprehensive guide, we‘re going to talk all about what a VPN server is, why it‘s critical for online privacy, and how to choose the best ones to meet your needs. Let‘s get started!
A Brief History of VPNs
Before we dive into the nitty gritty details, some background will help set the stage. VPN technology was originally developed in 1996 to help large corporations securely connect remote offices and employees to their company network over the public internet.
Soon people realized these same encrypted tunnels could also protect internet users‘ privacy and anonymity online. As internet speeds grew faster in the early 2000s, consumer VPN services took off, fueled by growing surveillance concerns.
Governments increasingly try blocking certain websites and apps. And snooping by ISPs and advertisers invaded people‘s privacy.
So VPN adoption soared. Today 91 million people use consumer VPN services to take control of their privacy and bypass restrictions. Those numbers continue rising rapidly as VPNs become mainstream.
Now let‘s examine what powers this vital privacy protection tool.
Defining a VPN Server
When you connect your device to a VPN service, all your web traffic is securely routed through an intermediary server run by the VPN provider. This remote VPN server handles encrypting, hiding and relaying your data to keep you safe online.
Specifically, a VPN server:
- Creates an encrypted tunnel for your traffic to flow through unseen
- Hides your IP address, location and device identity from the sites you visit
- Decrypts your traffic, reads the website address requested, and forwards it to that destination
- Retrieves the responses from websites and sends them back encrypted through the tunnel to your device
This rerouting conceals your digital footprint from government agencies, ISPs, hackers and advertisers lurking on the web.
So in essence, a VPN server acts like an armored guard escorting your data past all the dangers of the internet until it reaches its destination intact and secure.
Flavors of VPN Servers
Not all VPN servers are identical. Many VPN providers offer different types tailored to specific privacy tools, protocols, locations and use cases.
Standard servers are the most common, offering a basic encrypted tunnel through a given location. This allows you to browse securely or stream shows for other regions.
Double VPN routes your traffic through two separate servers for an extra layer of encryption. It ensures maximum anonymity when accessing sensitive information that requires utmost privacy.
Onion Over VPN encrypts and then sends your traffic through the Tor network for deep anonymity. Tor bounces communications around random nodes to disguise traffic sources and destinations.
Obfuscated servers hide the fact that you‘re using a VPN at all. This allows you to bypass advanced firewalls and other systems designed to block VPN connections.
P2P servers optimize torrenting downloads and uploads by ensuring unthrottled speeds, zero lag while gaming, and supporting peer-to-peer file sharing protocols.
Dedicated IP assigns you a unique IP address for your sole use while connected to assigned servers, preventing any conflicts with others sharing IP addresses.
How to Choose the Right VPN Server
With thousands of possible server options globally, the best approach depends on what you aim to access through your VPN tunnel.
As a rule of thumb, always choose a server located in or near the country and region you’re in. Connecting to a geographically close server provides faster speeds due to less lag. If speeds ever slow to a crawl, try another nearby server.
Check the server load percentage within your VPN’s dashboard or app. High load means more users competing for bandwidth on that server, resulting in potential speed reductions. Pick another server with less load.
While most standard servers work for general web browsing and hiding your tracks from ISPs, specialty servers give added functionality. Say you need to torrent some Linux distributions legally. A P2P optimized server ensures fast downloads without throttling.
Or if you’re a journalist securely contacting sources by encrypting everything up to the maximum level, route through a Double VPN server which passes all traffic through two layers of encryption on separate servers.
Get to know your various server options. Tailor your server connection to whatever you aim to do online during any given session for optimized performance and privacy.
Case Study: NordVPN and its 5000+ Servers
To see a wide range of server types and locations in action, let’s check out leading provider NordVPN and its 5100+ servers spread across 60 countries worldwide.
NordVPN is consistently rated as one of the top VPN services thanks to its large server network, reliable and fast connections, and helpful recommendations. Beyond standard VPN tunneling, NordVPN offers all the common specialty servers covered earlier.
Onion Over VPN secures communications to the highest degree to avoid surveillance. Double VPN chains your traffic through two servers to make it exponentially harder to trace. Obfuscated servers allow you to sidestep regional VPN blocking. P2P optimized servers enable unthrottled torrenting and video streaming.
NordVPN earns stellar ratings for providing reliable, high-speed connections in nearly every country. By default, you auto-connect through the fastest available server. Or pick manually based on current server load percentages shown for each location.
One standout feature is NordVPN‘s Threat Protection technology built directly into Windows and macOS apps. It blocks malicious sites and trackers from downloading onto your device without requiring a separate antivirus.
So if you seek the ultimate in worldwide server coverage, advanced privacy-enhancing servers, watertight security, and lightning-fast speeds, NordVPN fits the bill.
Why VPN Servers Are Vital for Privacy & Security
Let‘s recap why VPN servers deliver the core value proposition of a VPN in the first place – encrypting and securing all your online activities.
Without VPN servers scrambling and rerouting your traffic through encrypted tunnels, everything you did online would be exposed. Government agencies could monitor your every email. Advertisers would track your browsing to bombard you with "relevant" ads. ISPs could log and sell records of everywhere you go online.
That‘s why it‘s vital to research VPN providers thoroughly before you trust them as your gatekeeper. Confirm they own and operate their own servers under strict no logging policies without third party meddling. Server capabilities and network scale also weigh heavily.
A broader reach of servers across more regions means you‘re able to securely and reliably access internet content nearly anywhere. Specialized servers let you get the right tool for specific privacy jobs rather than a one-size-fits-all approach.
I hope this guide gave you a helpful overview explaining exactly what VPN servers do protect your data. Now you can make the most privacy-enhancing decisions choosing the best servers for your personal needs!
