E-Shield MAC address

I am a little confused about the mac address used for the e-shields. The standard mac in all the ethernet examples are: 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED. And everyone says use that, unless your shield comes with a sticker with an address.

Now my (two) shields have their own addresses, but they are 90-A2-DA-00-44-6B and 90-A2-DA-00-2F-94, but if I use either of them I get a compile error. I tried converting the them into hex with and online converter but that didn't work either. So how do I use these addresses?

How are you trying to use them?

The digit groups are hex values. 90-A2-DA-00-44-6B ==> 0x90, 0xA2, 0xDA, 0x00, 0x44, 0x6B

I was just using {90, A2, DA, 00, 44, 6B} (no 0x prefix). Thanks.
