Internet Tiers, POPs & IXPs 🌐

Tiers:
• Tier 1 – Global backbone (AT&T, NTT)
• Tier 2 – Regional (Airtel, Jio)
• Tier 3 – Local ISPs

POP (Point of Presence) – ISP's physical location (servers, routers)

IXP (Internet Exchange Point) – Where ISPs connect & exchange traffic for free!

This is how the internet stays connected. 🤝
