Comment 3 for bug 1288923

It occurs to me that some might argue that it doesn't matter what IP address the DHCP server has or whether it changes at some point in time. This might have been a motivation for not reserving DHCP IP address(es) like we do for the default router IP address.

There is a real problem with that argument. The problem is that it ignores the fact that our DHCP server doubles as the DNS server for the local subnet. It is critical that the DNS server's IP address be consistent and predictable because running instances lose their DNS server if it changes. An oversight in the current design.
