Plan your network infrastructure. Enter an IP address and CIDR notation to see network details, broadcast address, and usable host range.
A number-base converter changes a number between bases such as binary (2), decimal (10), octal (8), and hexadecimal (16).
Enter a valid number for the source base and choose the destination base. The converter applies positional-number rules.
Each digit’s allowed range depends on the base: for example, hexadecimal permits 0–9 and A–F.
Conversion does not change the underlying numeric value; it changes its representation.
It is useful in programming, networking, digital electronics, and learning how positional number systems work.
An invalid digit for the selected source base is a common reason for errors.
