Convert IP addresses to decimal integers and vice versa. Supports both IPv4 and IPv6 formats. Ideal for development, debugging, and network analysis.
Enter IP or number to start conversion
When you need to store IP addresses in a database or perform integer calculations on IP addresses in network programming, manual conversion is both time-consuming and prone to errors. The IP to Number Converter is designed to solve this exact problem. It converts standard IPv4 or IPv6 addresses into unique decimal integers, and vice versa. An IPv4 address is essentially a 32-bit binary number, while an IPv6 address is a 128-bit binary number. Through precise mathematical calculations, this tool converts them into unsigned decimal integers for easy storage and computation, while also supporting reverse conversion.
Q: What is the purpose of converting an IP address to a number?
A: Converting an IP address to an integer makes it easier to store in a database (saving space), perform range queries (such as determining if an IP falls within a specific subnet), or directly compare and calculate values in certain network protocols and algorithms.
Q: Why is the converted IPv6 number so large?
A: This is completely normal. Because an IPv6 address is 128-bit, the range of values it can represent is massive (2^128). The resulting decimal integer will naturally be a very large number, such as "42540766411282592856903984951653826560".
Before using, please ensure the entered IP address format is correct (dotted decimal for IPv4, colon-separated hexadecimal for IPv6). Selecting the correct address version is crucial; parsing an IPv6 number using IPv4 rules will lead to incorrect results. This tool performs pure mathematical conversions and does not verify whether the IP address is routable or valid on an actual network. When converting large IPv6 addresses, please be mindful of your programming language or system's ability to support extremely large integers.
When performing network programming or data analysis, converting between IPs and integers is a fundamental operation. A typical example is converting the IPv4 address "192.168.1.1" into the integer "3232235777", which can be calculated using a formula that treats each segment as a base-256 number. In databases like MySQL, functions such as INET_ATON() and INET_NTOA() are commonly used to achieve similar functionality. Please note that the integer representation of IPv6 far exceeds the typical integer range of 64-bit systems (2^63-1). In languages like JavaScript, you may need to use the BigInt type to handle these values and prevent precision loss.
