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?
Hi RudiC, at the moment I am starting from scratch. I will probably define the network I want to allocate against within the script, or maybe pass it in as an argument... either way, lets assume I have a 10.10.224.0/22 network (as an example) ... within the script I can already populate an array with the 'used' IP's in that range ... but my challenge is to find away of evaluating the ones that arent in use (free to use) within that range.
Sorry, but im not sure I understand the 2nd part of your question with those IPs you have given
