	Developments in DNS: Investigating Bind 8
	While many of these features are a ways off, network administrators must stay on top of emerging implementations when planning to meet future demands. When deploying an enterprise-scale DNS infrastructure, it's important to weigh the features and benefits of the implementations. Fortunately, DNS is one of the few services that work fairly well across multiple platforms. We were able to integrate Bind 8 running on RedHat Linux with DHCP on Microsoft Windows 2000 while mixing in various zones handled by NetWare 5. To our surprise, this beast actually works--a reminder that standards pay off when vendors implement them properly. Greg Shipley is a Chicago-based consultant.
