What is an IP address as an integer?

An IPv4 address is really a 32-bit number written as four bytes. 192.168.1.1 equals the integer 3,232,235,777. Databases, firewalls and scripts often store IPs as integers because comparing and ranging numbers is faster than parsing dotted strings.

How do I convert an IP address to hexadecimal?

Convert each of the four octets to two hex digits. 192.168.1.1 becomes C0.A8.01.01, or 0xC0A80101 as a single value. Hex IPs appear in some log formats, embedded configs and IPv6-mapped addresses.

Integers make IPs sortable and range-comparable — the format databases and firewalls store internally. See the subnet calculator for network math.

Why convert IP addresses?

The dotted-decimal form (192.168.1.1) is for humans; computers see a plain 32-bit number. Storing IPs as integers lets a database answer "is this address inside this range?" with a single numeric comparison instead of parsing text, which is why access logs, geolocation tables and firewall rule engines all work in integers under the hood. Hex shows up in embedded device configs, some log formats, and when mapping IPv4 into IPv6. Binary is where the subnet mask logic actually happens — seeing the bits makes CIDR click.

Frequently asked questions

What is an IP as an integer?

A 32-bit number — 192.168.1.1 = 3,232,235,777. Faster to store, sort and range-compare than dotted text.

How do I convert an IP to hex?

Each octet becomes two hex digits: 192.168.1.1 → 0xC0A80101 (or C0.A8.01.01 grouped).
