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

ifcfg-wireless

IFCFG(5)						       Network configuration							  IFCFG(5)

NAME

       ifcfg-wireless - wireless LAN network interface configuration

SYNOPSIS

       /etc/sysconfig/network/ifcfg-wlan-*
       /etc/sysconfig/network/ifcfg-type-wlan

GENERAL

       Wireless  networks  need  some additional configuration data compared to ethernet ones. Therefore additional variables for ifcfg files were
       introduced.  All wireless LAN specific variables are described in the ifcfg template file /etc/sysconfig/network/ifcfg.template. It is pos-
       sible to configure more than one wireless network accepted for association. To achieve this add suffix _1 to all wireless variables for the
       second network, _2 for the this, and so on. Example: WIRELESS_ESSID_1="second_net" You can have up to  ten  wireless  networks  configured.
       Some  wireless  variables  are not applicable to a single wireless network but are global to the interface. The description of the variable
       points this out.
