It would be nice if you said a few things (since you're plannng for this to be a series) about DHCP in production environments. Typically I've seen DHCP used to handle desktops, but a lot of people are a bit wary of using it to assign IPs to production servers. This leaves the problem of how to administer large production environments using DHCP. On the one hand, it's a hassle to assign IPs manually and on the other hand if the DHCP server goes down and someone tries to renew a lease, you lose a production system temporarily, and perhaps you lose more than one. I know that failover and redundancy or on the horizon for ISC's dhcpd, but that's only part of the solution...

  A common solution when using DHCP with servers is to have a reasonable renew time but a long expire time. That way if you lose DHCP service you won't find half of your servers without IP addresses.
  
  You can also easily setup a backup DHCP server that comes online if it detects the primary DHCP server has died. This can be done manually and can be quite effective.
  
  Perhaps an article re: DHCP and servers is not a bad idea.
  
  I personally much prefer to use DHCP when assigning IPs to servers. However, there are some obvious security issues that must be considered.
