Virtual LAN (VLAN) is a Layer 2 technique that allow for the coexistence of multiple local area network (LAN) broadcast domains, interconnected via trunks using the IEEE 802.1Q trunking protocol. Other trunking protocols have been used but have become obsolete, including Inter-Switch Link (ISL), IEEE 802.10 (originally a security protocol but a subset was introduced for trunking), and ATM LAN Emulation (LANE).
However, network performance is another thing entirely. First, keep in mind that if you're using a VPN, you're probably using it at a public location. That Wi-Fi service is likely to range in performance somewhere between "meh" and unusable. So, just the fact that you're remotely working on a mediocre network will reduce performance. But then, if you connect to a VPN in a different country, the connection between countries is also likely to degrade network performance.
With  multiple clients, rich with different features, it’s no wonder this VPN service handles more than 10 million users. CyberGhost covers Microsoft’s and Apple’s operating systems, but also iOS and Android. The interface is not the best out there and could definitely use some work, but these disadvantages are easily overshadowed by the awesome features this VPN offers.
Tunnel endpoints must be authenticated before secure VPN tunnels can be established. User-created remote-access VPNs may use passwords, biometrics, two-factor authentication or other cryptographic methods. Network-to-network tunnels often use passwords or digital certificates. They permanently store the key to allow the tunnel to establish automatically, without intervention from the administrator.
Most Economical or Cheapest VPN: Private Internet Access’s global network of VPN servers lets you to hide in plain sight for less. With more than 3,200 servers in 33 countries, Private Internet Access (PIA) connects in places like Germany, Turkey and Singapore but lacks VPN servers in hot spots like Russia. It pales in comparison to the 190 countries that Hide My Ass operates in. The service encrypts your traffic, can obscure your location, block ads and malware as well as including a capable firewall. There’s software for Windows (7, 8 and 10), Mac OSX (10.13), Linux, iOS and Android. It also works with Chrome, Firefox, Opera browsers and some open-source routers. The small Windows interface lets you pick a dark or light color scheme, set the encryption level and use small data packets for greater reliability. There’s a mini world map but you must use PIA’s assigned log-in name. While PIA doesn’t keep connection logs, its Denver headquarters means that American spy agencies can potentially snoop on your Web journeys. At $7 per month or $3.33 a month for a year, PIA is a bargain that allows 5 simultaneous users. In other words, PIA provides a lot of VPN security for the money.
When you browse the web while connected to a VPN, your computer contacts the website through the encrypted VPN connection. The VPN forwards the request for you and forwards the response from the website back through the secure connection. If you’re using a USA-based VPN to access Netflix, Netflix will see your connection as coming from within the USA.

Tip for Chrome, Firefox, and Opera users: A feature called WebRTC can, in some Web browsers, inadvertently cause your true IP address to leak out even when you’re connected via a great VPN. WebRTC assists with peer-to-peer connections, such as for video chatting, but could be exploited in some cases. You can manually disable this function in Firefox, or use an extension to block most instances of it in Chrome or Opera. For more details and instructions, check out Restore Privacy.

There are some minor disadvantages to using a dynamic IP. If someone who previously had the IP address you've been assigned did something nefarious on a service you use, it's possible that IP address might be banned. Usually, VPN providers are very careful about checking their IP addresses against blacklists, so the chances of this being a problem for you are slim.
A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. VPNs mask your internet protocol (IP) address so your online actions are virtually untraceable. Most important, VPN services establish secure and encrypted connections to provide greater privacy than even a secured Wi-Fi hotspot.

Private Internet Access' client interfaces aren't as flashy or cutesy as some other services' software, but they're clear and simple enough for newbies to start right away. A toggle switch reveals all the settings a VPN expert would ever want to play with. You can also skip Private Internet Access' software and connect directly to the servers, or use a third-party OpenVPN client.


Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We're pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors' Choice nod both for desktop VPN apps and Android VPN apps.
— Mullvad has added iOS support for the new WireGuard VPN protocol. The service has also added an onion site at http://xcln5hkbriyklr6n.onion/ so that Tor users can get Mullvad accounts and download software completely anonymously. It is also urging users to upgrade their client software to at least version 2018.5, as earlier versions will not be supported after March 22, 2019.
VPNs initially are corporate networks ensuring safely encrypted connections between the company server and the employees. These systems give colleagues who are in different departments the possibility of collaborating without physical contact. VPNs are helpful and assist in office maintenance by allowing their employees to work from anywhere in the world or remotely in the comfort of their homes. The application and use of VPN technologies were started by the Chinese who were after getting the around the restrictions of the great firewall.
A popular VPN service, TorGuard has servers in over 50 countries and enables users to unblock websites and get around censorship. This ensures that wherever you are in the world, there is bound to be a TorGuard server near you. By default, the service enables users to make five simultaneous connections. This lets users run the service on all their devices. To better protect users, the service has a kill switch. However, this feature is not available on mobile devices. Likewise, a Domain Name System leak protection works on Windows and OS X.

Windscribe's network performance was once about average in our tests, but a recent switch in VPN protocols put it on par with Private Internet Access in head-to-head tests. Windscribe is compatible with many platforms (including routers and Amazon Fire and Kodi TV set-top boxes), offers a wide variety of connection options, has a wide geographic reach with hundreds of servers, and presents an appealing, if minimal, user interface. It was also one of the best at connecting to Netflix U.K. and BBC iPlayer, if you're into that sort of thing.

ExpressVPN has a wide range of client software, a dedicated proxy service for streaming media and its own DNS service. But in our 2017 tests, it dropped many connections and its overall performance was in the middle of the pack. It also allows only three devices to be connected simultaneously per account, and it's one of the most expensive services we evaluated.


First, the good: IPVanish features solid encryption, unlimited bandwidth, and lets you connect up to five devices simultaneously. The Android app offers a clean dark theme and is easy to use for beginners, with features that advanced users will appreciate. Connecting to and switching between servers is quick and easy as well making the overall user experience pretty great.
They even offer the most generous simultaneous connection count, with six simultaneous connections through their network, where everyone else offers five or fewer. NordVPN's network isn't as large as some of their competitors, so if you're trying to obfuscate your tracks, you might want a company with more servers. Otherwise, this company is clearly providing a winning offering.
