I was speaking more generally about servers, not specifically about Myth. As

server are off the map.

And I trust a static IP on my web servers and mail servers to keep working

I don't think whether DHCP is a good or bad idea was even the debate. I never 
said DHCP was bad, I happily use it both at home and at work. I believe the 
debate was over whether servers getting an IP via DHCP was a good or bad
