I'm sure when they said "any way you want", they meant "any way that works". In particular, though, you can't assign another name without first registering it. Well, you can, but it won't work. Any I suspect that you might have set your broadcast address on IP 41 incorrectly. If that's your block, your broadcast address should be 206.14.149.63, and your net mask should be 255.255.255.192.
