Free online IPv4 address format converter for network engineers. Convert between decimal, hexadecimal, binary, and dotted notation formats.
Converts an IPv4 address between its four common representations: dotted-decimal, 32-bit integer, hexadecimal, and binary. Enter an address in any format and instantly see all four conversions along with a per-octet breakdown showing decimal, binary, and hex values.
Network engineers, security analysts, and developers frequently need to translate IPv4 addresses between formats for logging, ACL configuration, forensics, and protocol debugging. Doing this mentally or with scattered online tools is slow and error-prone.
Network engineers writing ACLs, security analysts investigating IP logs, developers working with socket APIs, and students studying binary number representation.
Select your input format from the dropdown (dotted decimal, integer, hexadecimal, or binary)
Enter the IPv4 address in the chosen format
Press Convert or hit Enter to see all four representations
