What is a VPN?
A VPN, or Virtual Private Network, extends a private network across a public one. It enables users to send data across shared networks as if their devices were directly connected to the private network.
VPN Encryption Protocols
VPNs use protocols like OpenVPN, L2TP/IPsec, and IKEv2 for secure tunnels. OpenVPN is favored for its balance of speed and security. IKEv2 excels in re-establishing lost connections quickly.
Unexpected VPN Benefits
Beyond privacy, VPNs can bypass geo-restrictions, allowing access to content worldwide. They can also reduce ISP throttling, potentially increasing internet speeds during bandwidth-heavy activities.
VPNs and Online Anonymity
VPNs mask IP addresses, making user activities harder to track. However, anonymity isn't guaranteed. VPNs don't make you invisible online; they simply make tracking you more difficult.
Choosing a VPN Provider
Selecting a VPN service requires scrutiny. Look for a no-logs policy, strong encryption, reliable protocols, and positive user reviews. Beware of free VPNs; they may monetize your data.VPNs in North Korea
