Online conversion to CIDR and aggregation of a large number of IP ranges
This service is intended for converting ranges of IP addresses, written with a hyphen (or separated by a space or a colon) in CIDR notation, with subsequent merging of networks, if possible.
Each range should be placed on a separate line. An example of IP ranges in the correct format can be found below.
