IPv4 prefix list builder

Enter in IP prefix information in the box below to automatically create sorted static route statements, access lists, BGP commands, or prefix lists. The program will attempt to extra the data from common formats such as running configs, "show ip route", "show ip bgp" etc by removing non-relevant data and looking for a network address followed by a prefix length, netmask, or wildcard/hostmask. With the guess option enabled, network addresses followed by a next-hop (common for classful addresses in Cisco ISR BGP output) will attempt to use the correct classful prefix length.

Examples of acceptable formats include:


Enter your IP prefix information in the above box.
