Perl script to allocate next available IP from a range
Hi
I am looking to automate the process in PERL of allocating IP addresses from a set range of addresses (for example a /22 network 10.10.224.1 - 10.10.227.254)
I am able to query the IP addresses that are already in use in the above range, which will produce me a list like this for example
What I am trying to do is find a way of taking that list and determining the next available IP address for use within the boundaries of the netmask (so for example between 10.10.224.1 and 10.10.227.254) Naturally if this was just a standard list of numbers then it would be straightforward, but given they are IP addresses, its a bit more complex
does anyone know a good starting point for this or have any experience of setting up something similar?

netmask
NETMASK(1) Debian Linux NETMASK(1)NAME
netmask - a netmask generation and conversion program
SYNOPSIS
netmask [ options ] spec [ spec ... ]
DESCRIPTION
This program accepts and produces a variety of common network address and netmask formats. Not only can it convert address and netmask
notations, but it will optimize the masks to generate the smallest list of rules. This is very handy if you've ever configured a firewall
or router and some nasty network administrator before you decided that base 10 numbers were good places to start and end groups of
machines.
OPTIONS -h, --help
Print a summary of the options
-v, --version
Print the version number
-d, --debug
Print status/progress information
-s, --standard
Output address/netmask pairs
-c, --cidr
Output CIDR format address lists
-i, --cisco
Output Cisco style address lists
-r, --range
Output ip address ranges
-x, --hex
Output address/netmask pairs in hex
-o, --octal
Output address/netmask pairs in octal
-b, --binary
Output address/netmask pairs in binary
-n, --nodns
Disable DNS lookups for addresses
DEFINITIONS
A spec is an address specification, it can look like:
address
One address.
address1:address2
All addresses from address1 to address2.
address1:+address2
All addresses from address1 to address1+address2.
address/mask
A group starting at address spanning mask.
An address is an internet network address, it can look like:
ftp.gnu.org
An internet hostname.
209.81.8.252
A standard dotted quad internet address notation.
100 A decimal number (100 in this case).
0100 An octal number preceded by "0" (64 in this case).
0x100 A hexadecimal number preceded by "0x" (256 in this case).
A mask is a network mask, it can look like:
255.255.224.0
A dotted quad netmask (netmask will complain if it is not a valid netmask).
0.0.31.255
A Cisco style inverse netmask (with the same checks).
8 The number of bits set to one from the left (CIDR notation).
010 The number of bits set to one from the left in octal.
0x10 The number of bits set to one from the left in hexadecimal.

BUGS
Let me know if you find any. This man page is a bit more simplistic than I'd like, but I've forgotten most of the groff I once knew.
