IP address and numeric address converter

The IP-to-integer tool converts between an IP and an integer, turning an IP address into a decimal number, an IP address into a LONG number and an Int number into an IP address. Paste it in the browser and access it just like the IP. A numeric address is a place's digitized geographic location on the international numeric address network.

IP and integer converter

A digital address is one kind of IP address: the digitized form of an IP address

Copy it; accessing it in a browser is the same as accessing an IP. A numeric address is the digital geographic location of a place on the international numeric address web

A digital address is the digital geographic location of a place on the International Digital Address Network

Enter the numeric address directly in the browser to look up the location's network geography; it is simply another form of a network address

In a browser, visiting http://66.102.7.147 has the same effect as visiting http://1113982867


How to convert an IP address to a numeric address:

Example: 66.102.7.147

The calculation process is as follows:

Formula: 66*256^3+102*256^2+7*256+147=1113982867

The converted 1113982867 is the numeric address of IP 66.102.7.147

How to use

This tool belongs to the “Encryption & encoding” category.

  1. 1Pick an algorithm: reversible ones are AES, DES and RC4; one-way digests are MD5 and the SHA family.
  2. 2Enter the text plus your key or salt. Encrypting twice with the same key must give the same result.
  3. 3Copy the output into your code. When comparing digests, match case and the 16/32-bit variant first.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

Can MD5 be decrypted?

No. MD5 is a one-way digest — you can compare it, never reverse it. So-called "decryption" is a rainbow-table hit.

Why do two runs give different results?

Salts, random IVs, or a different case or source encoding all change the output. Normalise to UTF-8 before comparing.

Is it safe to paste a real key here?

Use it for learning and format checks. Generate and store production keys server-side; never paste a live secret into a web page.
