Can a hacker really do anything with your IP address?

Your IP address won't give a hacker your passwords, yet it can point attackers to your home network. Here's what IPv6 changes and how to stay protected.

IP addresses are among the digital footprints left behind while surfing the internet. Many users think that if this number sequence falls into the hands of cyber hackers, all their personal accounts can be compromised. However, the real threat dimension is quite different from what is thought. Although an IP address alone does not reveal passwords, it can create a critical target point for cyber attackers.

Limits of IP Address and the Risks It Exposes

The IP address that identifies the network connection does not directly contain sensitive information such as banking passwords, e-mail logins or credit card data. Therefore, an attacker who only learns the IP number cannot directly access user accounts. However, this combination of numbers makes visible the service provider to which the device is connected, the approximate geographical location and open network ports. Hackers use this address as a springboard to scan for vulnerabilities on the target device and launch direct port scans or denial-of-service (DDoS) attacks.

Precautions to be Taken for Individual Users and Network Security

When attackers target the IP address, it can pose serious risks, especially when modems and routers in home networks are left with default passwords. Malicious actors can monitor network traffic by remotely hijacking routers with unupdated software. To prevent possible tracking and direct targeting attempts, experts recommend regularly updating modem firmware, choosing strong administrative passwords, and using virtual private network (VPN) services when necessary. Even restarting the modem for subscribers using dynamic IP is considered an effective first step in defeating instant targeting.
