Online lore makes "having someone's IP" sound like a master key. It's not. But it's also not nothing. Here's what an attacker can and can't do with just your public IP.

What they can't do (despite what TV says)

• Read your messages
• See your screen
• Steal your passwords
• Access your files
• Turn on your camera

None of these are possible from an IP alone. They require either malware on your device or credentials.

What they CAN do

• Port scan you — probe for open services on your router (SSH, RDP, IoT admin pages). If anything's exposed and unpatched, that's the foothold.
• Launch a DDoS — flood your IP with traffic. Annoying for online gaming, mostly harmless beyond inconvenience for home users.
• Look up your rough location — see how precise IP geolocation actually is.
• Use it for social engineering — "I see you're in Dallas, want to meet?" type tricks.

The real risk: open ports

The danger isn't the IP — it's what's listening on it. Routers ship with admin pages, IoT cameras with default passwords, NAS boxes with file shares exposed. An attacker with your IP scans for these and pokes at any default credentials. Most home users have nothing exposed because NAT blocks inbound by default. Risk only appears when you forward ports or run UPnP.

How to protect yourself

• Disable UPnP on your router
• Don't forward ports unless you know exactly what's behind them
• Change all default device passwords
• Keep router firmware updated
• Use a VPN when on public Wi-Fi or if you've been targeted

If you've been DDoS'd

Power-cycle your router. Most ISPs reissue a new public IP when the lease renews — the attack is keyed to the old IP, so the flood stops. If you have a static IP or it doesn't change, contact your ISP.
