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

Code:
10.10.224.1
10.10.224.2
10.10.224.3
10.10.225.23
10.10.225.35
10.10.227.67
...
...

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?

Cheers

pob-fec

POB-FEC(1)							   User Command 							POB-FEC(1)

NAME

       pob-fec - receive FEC MP3 streams

SYNOPSIS

       pob-fec [ -s address ] [ -p port ] [ -b size ] [ -q ]

DESCRIPTION

       pob-fec	receives  a  FEC MP3 stream using a custom protocol. The streamed MP3 frames are first decomposed in autonomous data units (ADUs).
       These ADUs are grouped into ADU groups, which are encoded redundantly using a FEC method by Luigi Rizzo. For example, a group if 8 ADUs can
       be  encoded  into  16  packets.	Any  8 received packets of these 16 packets is sufficient to recover the original 8 ADUs. The incoming MP3
       stream is decoded, buffered and written to stdout.

OPTIONS

       -s address
	      Specify the address to listen to (default 224.0.1.23). If the address is a multicast address, group membership is requested automat-
	      ically.

       -p port
	      Specify the port to listen to.

       -b size
	      Specify the number of ADU groups that are hold in the buffer (default 16).

       -q     Don't output any information on standard error.

EXAMPLES

       pob-fec -s 224.0.1.24 -p 8989 | mpg123 -
	      Receive the MP3 FEC stream sent to 224.0.1.24 on port 8989 and feed it into the MP3 decoder mpg123.
