You would also get a match on "ballerup-w" for a hostname of "something-ballerup-w". If you want it to match exactly, you need to anchor it to the start and end of the string, using "^" for the start, and "$" for the end. For example:</div>
<div><br></div><div>$somelist=%^(host1|host2|host3)$</div><div><br></div><div>This means, in English, "start of string, immediately followed by one of host1, host2, host3, immediately followed by end of string".</div>
<div><br></div><div>With your problem, you probably don't need anchoring to the start, because the only ambiguity is at the end of the hostname ("ballerup-w" vs "ballerup-w-plnet"). Nevertheless, to future-proof, you probably should anchor to the start of the string.</div>
