IP to Decimal Converter

What is IP to Decimal?

IP to Decimal converts an IPv4 or IPv6 address into its decimal number representation. This is useful for databases, low-level networking, and comparing or sorting IP ranges without dotted or colon formats.

How does the converter work?

For IPv4, the four octets are combined into a 32-bit integer. For IPv6, each hextet is expanded and combined into a 128-bit integer. Input validation ensures you get a clean decimal output or a helpful error if the address is invalid.

• Enter any valid IPv4 (e.g., 192.168.0.1) or IPv6 (e.g., 2001:db8::1).
• Click Convert to get the decimal value instantly.
• Copy or download the decimal output for logs, databases, or automation.

Why convert IP to decimal?

Decimal IPs make it easy to compare ranges, store values in databases, and perform numeric operations. Network tools and security scripts often rely on decimal formats for sorting, filtering, and range checks.

• Range math: Quickly see if an IP falls within a CIDR block.
• Database storage: Store IPs as integers to improve indexing and comparisons.
• Automation: Scripts and firewalls can work directly with decimal values.

Frequently Asked Questions

What is an IP to decimal converter used for?

It turns IPv4 or IPv6 addresses into their integer representation. This is helpful for IP range math, ACL comparisons, database storage, and networking scripts.

Does it support IPv6?

Yes. Compressed IPv6 (with ::) and embedded IPv4 are parsed into the correct 128-bit integer value.

Can I convert the decimal back to an IP?

You can use our Decimal to IP tool to reverse the conversion for both IPv4 and IPv6 integers.

Is my input stored or sent to a server?

No. The conversion runs locally in your browser; LambdaTest does not log your IP data.

Can I process multiple IPs at once?

Yes. Paste multiple lines and the tool will output each IP on its own line in decimal form, ready to copy or download.
