Streaming services such as Netflix, Disney+, Hulu, BBC iPlayer, NRK TV and many others check your IP address before deciding what content you are allowed to watch. Depending on where you are located, a service may offer a different catalogue, or it may block access completely. If you travel abroad you may discover that content available at home is suddenly unavailable.

This is where a Virtual Private Network (VPN) can help. A VPN allows you to route your internet traffic through a server in another location, making it appear as though your connection originates from that country or region. Another solution is to use a proxy server, but there are important differences between the two technologies.

The purpose of both VPNs and proxy servers is to conceal your real IP address and present a different location to websites and online services. This can be useful when accessing geo-restricted content, protecting privacy, or securing connections on public Wi-Fi networks.

A proxy server acts as an intermediary between your device and the internet. Traffic appears to come from the proxy server instead of your own connection. Proxies are often faster because they usually do not encrypt traffic, but this also means they provide much less security and privacy. Some free public proxies are unreliable, may log activity, and can expose your data to third parties.

A VPN works differently. It creates an encrypted tunnel between your device and the VPN server. All network traffic passing through the tunnel is protected from local network operators, public Wi-Fi providers and internet service providers. Modern VPN services typically use protocols such as WireGuard or OpenVPN and strong encryption standards such as AES-256 or ChaCha20.

While a VPN hides your browsing activity from your internet provider, it does not make you anonymous. The VPN provider itself can potentially see certain information about your connection. This is why it is important to choose a provider with a transparent privacy policy, independent security audits and a proven reputation for protecting user data.

Despite being originally designed for corporate and private networking, VPNs have become popular tools for consumers. Once configured, a VPN protects traffic from web browsers, e-mail clients, streaming applications, online games and most other internet-connected software.

Modern VPN services are generally much faster than earlier generations. In the past, VPN connections could significantly reduce internet speed. Today, high-quality VPN providers often have minimal impact on performance, especially when using WireGuard and nearby servers.

VPN and Streaming Services

A VPN may allow you to access content libraries from other countries, but there are some limitations.

Streaming companies actively attempt to detect and block VPN traffic. A VPN server that works with a particular service today may stop working tomorrow. Reputable VPN providers usually maintain large numbers of servers and frequently rotate IP addresses to remain functional.

Before subscribing to a VPN service specifically for streaming, it is worth checking whether the provider currently supports the streaming platforms you intend to use.

Keep in mind that using a VPN to bypass geographical restrictions may violate the terms of service of some streaming providers. Users should review the applicable terms before proceeding.

Free VPN vs Paid VPN

You generally have two options when selecting a VPN service: free or paid.

Free VPN services may be suitable for occasional use, but they often have limitations such as:

• Lower speeds

• Data caps

• Fewer server locations

• Streaming restrictions

• Advertising

• Reduced privacy protections

A quality paid VPN service typically offers:

• Faster connections

• Better streaming support

• More server locations

• Stronger privacy features

• Customer support

• Advanced security tools

Many providers also include features such as:

• Kill switch protection

• DNS leak protection

• IPv6 leak protection

• Multi-factor authentication

• Malware and tracker blocking

• Multi-hop routing

DNS Leaks

A DNS leak occurs when DNS requests bypass the VPN tunnel and are sent directly to your internet provider or another resolver. This can reveal information about websites you visit even when a VPN is active.

DNS leaks are not limited to any specific operating system. They can occur on Windows, macOS, Linux, Android and iOS if the VPN is improperly configured.

Most modern VPN applications include built-in DNS leak protection. If you wish to verify that your connection is working properly, several online DNS leak testing services are available.

Choosing a VPN Provider

When evaluating a VPN provider, consider:

• Independent security audits

• Privacy policy and logging practices

• Server locations

• Streaming support

• Connection speed

• Country of jurisdiction

• Customer support

• Multi-platform compatibility

Do not choose a provider solely because it is the cheapest. Security, transparency and reliability are often more important than saving a few dollars per year.

Final Thoughts

A VPN remains one of the most useful tools for improving online privacy, securing internet connections and accessing content while travelling. However, a VPN is not a magic cloak of invisibility. It should be viewed as one component of a broader privacy and security strategy that includes strong passwords, multi-factor authentication, software updates and sensible browsing habits.

Used correctly, a reputable VPN service can provide both convenience and additional protection while using today's increasingly connected internet.
