IPv4 to Integer Converter — IP Address to Integer Online
Convert IP address to integer — decimal and hexadecimal from any IPv4.
Introduction
IPv4 to integer converter online — map dotted-decimal addresses to a single 32-bit number for databases, GeoIP APIs, and sorting. Also works as an ipv4 to integer calculator with hex output.
How to use this ipv4 to integer converter tool
- Enter IPv4 (e.g. 8.8.8.8).
- Click Convert.
- Copy decimal or hexadecimal output.
What Is This Tool?
Convert IP address to integer using the standard formula: each octet contributes to a 32-bit unsigned value (a×256³ + b×256² + c×256 + d).
Developers use ipv4 to integer conversion when storing IPs in numeric columns or comparing ranges in SQL.
How to Use This Tool
- Enter IPv4 (e.g. 8.8.8.8).
- Click Convert.
- Copy decimal or hexadecimal output.
Formula / Calculation Logic
Integer = (octet1 << 24) + (octet2 << 16) + (octet3 << 8) + octet4, unsigned 32-bit.
Examples
Sample inputs and expected outputs:
| Input | Result |
|---|---|
| 8.8.8.8 | 134744072 |
| 192.168.1.1 | 3232235777 |
| 0.0.0.0 | 0 |
Understanding Results
- Decimal — unsigned 32-bit value.
- Hex — same value in hexadecimal.
Use Cases
- Database IP columns
- GeoIP APIs
- Sorting IP lists
- CTF challenges
Benefits
- One-click copy
- Validates octets
- Shows hex for debugging
Common Mistakes
Avoid these errors when using this network calculator:
Planning pitfalls
- Using signed integers above 2^31
- Leading zeros or five octets

ipv4 to integer converter — frequently asked questions
A IPv4 to integer converter applies standard IPv4 subnet math (RFC 950 / CIDR) to compute network boundaries, masks, and host counts without manual binary conversion.
You enter IPv4 addresses, masks, or CIDR notation. The calculator bitwise-ANDs the address with the mask to find the network ID, then derives broadcast, wildcard, and host ranges.
Use it during CCNA study, VPC design, firewall rule documentation, IPAM planning, and troubleshooting when you need quick confirmation of subnet boundaries.
Yes. VSPIC runs calculations in your browser with no account required.
These calculators focus on IPv4. For IPv6 prefix planning, use our IPv6 Test and IP Subnet Calculator IPv6 tab.
CIDR writes the prefix length after a slash (e.g. /24). It replaces legacy classful networks and is used in routing tables worldwide.
A subnet mask marks which bits belong to the network portion. A /24 equals 255.255.255.0 with 254 usable hosts in typical subnets.
Yes. RFC 1918 addresses (10.x, 172.16–31.x, 192.168.x) use the same subnet mathematics as public space.
Set all host bits to 1 in the subnet — bitwise OR of network address with the inverted mask.
Variable Length Subnet Masking uses different prefix lengths within one parent network to minimize wasted addresses.
Enter the IPv4 in the converter and click Convert. The ipv4 to integer converter online returns unsigned decimal and hexadecimal — copy either for your database or API.
It turns human-readable IPs into numbers for SQL BETWEEN queries, log analytics, and IP range indexes without manual binary math.
