5 Tips for Working with IP Addresses

5 Tips for Working with IP Addresses

1. Distinguish Public and Private Addresses

Private addresses (10.x.x.x, 192.168.x.x) are not routed on the internet. Don't confuse them with public ones when configuring servers.

2. Validate IPs in Configurations

A typo in a configuration IP address can make a service unavailable. Always check addresses before applying.

3. Use CIDR Notation

Instead of specifying ranges, use CIDR: 192.168.1.0/24 defines the entire subnet of 256 addresses.

4. Log and Analyze IPs

When investigating security incidents, validating IPs from logs helps filter out incorrect records.

5. Prepare for IPv6

IPv4 addresses are running out. Make sure your systems support validation of both formats.

Useful Checks

Check addresses with the IP Validator.
