in reply to How to convert MAC address to IP address ?

Although it might be clear, I think it should be stated for those who do not know: the MAC address of a network card is relatively fixed by the hardware (disregarding spoofing and such), whereas an IP address can vary greatly, based on the network, DHCP, and other factors. Thus, there is no way to simply convert from a MAC address to an IP address with no further information.

But of course, you probably have more information. In that case, see the referenced nodes in the above replies.

    Download angry ip scanner, select the extra column MAC Address in the options and do a ping sweep of your network, this is the easiest way to do it.

[hippo]: The more I look at this code, the more $x is a plain old scalar and the more this condition will never be true. I'm calling it a bug at this point.
[hippo]: Thanks for your input which has soothed my sanity (a little)
[Corion]: Eily: Sure - if you force both things into stringy things, then you break that magic. But that would also mean that you changed the expression, as now $x = 0.00 will be true instead of false as it were before
[Corion]: Ah no, at least in my feeble experiments that doesn't change the meaning
[Corion]: We sell sanity in small packages ;)
[Eily]: oh, boolean context uses the "" overload if no bool overload has been defined
[Eily]: (I wondered if overloading bool was actually necessary)
