NAME
prips -- print the IP addresses in a given range SYNOPSIS
prips [-c] [-d delim] [-e exclude] [-f format] [-i incr] start end prips [-c] [-d delim] [-e exclude] [-f format] [-i incr] CIDR-block prips -h DESCRIPTION
The prips tool can be used to print all of the IP addresses in a given range. It can enhance tools that only work on one host at a time, e.g. whois(1). The prips tool accepts the following command-line options: -c Print the range in CIDR notation. -d delim Set the delimiter to the character with ASCII code delim where 0 <= delim <= 255. -e <x.x.x,x.x> Exclude ranges from the output. -f format Set the format of addresses (hex, dec, or dot). -h Show summary of options. -i incr Set the increment to 'x'. ENVIRONMENT
The prips tool's operation is not influenced by any environment variables. FILES
The prips tool's operation is not influenced by any files. EXAMPLES
Display all the addresses in a reserved subnet: prips 192.168.32.0 192.168.32.255 The same, using CIDR notation: prips 192.168.32/24 Display only the usable addresses in a class A reserved subnet using a space instead of a newline for a delimiter: prips -d 32 10.0.0.1 10.255.255.255 Display every fourth address in a weird block: prips -i 4 192.168.32.7 192.168.33.5 Determine the smallest CIDR block containing two addresses: prips -c 192.168.32.5 192.168.32.11 DIAGNOSTICS
The prips utility exits 0 on success, and >0 if an error occurs. SEE ALSO
ipsc(1), gipsc(1) STANDARDS
