Thanks Eric. Those are what I was going to use before I had the thought that someone might know of an already built function I could use rather than me taking the IP and netmask apart, applying those, and reassembling the IPrange. I suppose I've already wasted more time than I would have saved. :) On Thu, Oct 27, 2011 at 10:28 AM, Eric Shubert <[email protected] <mailto:[email protected]>> wrote: On 10/26/2011 09:49 PM, Dazed_75 wrote: I would like to apply a netmask to an arbitrary IP in a bash/dash script (e.g. apply 255.255.255.0 to 173.10.3.155 to get 173.10.3.0). Is there any easy way to do that without taking the IP apart, doing 4 operations and reassembling the results? -- Dazed_75 a.k.a.
