What is a private network and how do VPS servers communicate privately?
A private network (also called internal or local network) allows multiple VPS servers to communicate with each other via private IP addresses that are not accessible from the internet, improving security and performance. Use cases: web server communicating with database server over private network (database port never exposed to internet), multiple app servers sharing a Redis cache, and backend services calling each other without SSL overhead. On Connect Quest, request private networking between VPS instances in the same data center — they get private IPs (10.x.x.x) in addition to public IPs. Configure your web server to connect to MySQL at the private IP (10.0.1.2) instead of public IP. Firewall rules: block MySQL port 3306 from public internet, allow from private network only. Private network traffic is free (no bandwidth counting) and latency is sub-millisecond within the same data center. Contact +91 2269711150 to set up private networking on Connect Quest.
