Confused a little: How can DHCP manage IP addresses it considers out of scope? Or are you referring to the idea that DHCP is allowed to register DNS addresses perhaps?
As for the differences? Having used both, I'd say both have plusses and minusses. On the plus side, QIP is pretty feature rich and shops that have their DHCP/DNS controlled by the networking folks, have often picked this setup for the features it provides. It's not a lot of features, but for some they are important. On the minus side, it can be expensive to own DNS/DHCP if you pay for QIP. I've seen shops that spent a TON of money to own the same features they could have had with BIND and last I checked QIP doesn't support the concept of authenticated updates. It's either permission the zones or don't, but you can't use active directory authentication to allow DDNS updates. That sucks. Additionally, since it's a third party app, you will run into issues where you can't update the host it runs on due to incompatability; btdt :) To say you can't manage Microsoft's DNS/DHCP just tells me you're not into scripting. It's all available, it's just not all in the GUI. Personally, I'd trade authenticated updates/cost of ownership over some of that functionality. I can create DNS zones for IP addresses that DHCP doesn't manage. I can create scopes that cover all of my ip address ranges, just some hosts wouldn't use the DHCP scope, right? Plenty of ways I can do this solution based on the network and the hard and fast requirements vs. the nice to have ideas. Management of IP addresses is ambiguous outside of your organization; we need some background to understand what they mean. FWIW, some of the largest networks out there use Microsoft DNS/DHCP and do so just fine. Yours would be a pretty small network comparatively speaking ;) Here's a nice glossy faq that gives some contrast as well: http://www.lucent.com/livelink/0900940380026b9c_FAQ.pdf My thoughts anyway.

We currently have a mish-mash of Microsoft DNS and DHCP in use as well as QIP (outdated and not supported) for these services. Our network group is strongly in favor of an overall IP address management tool such as QIP or MetaIP for DNS and DHCP as these are just part of the capability of the tools. The real value to those tools lies outside of merely DHCP and DNS. They need to what device is on what address and/or whether the address is available, regardless of whether it's part of a DHCP scope or not. We also have ping blocked throughout most of the environment in response to the viruses/worms that came out some time ago. We're 65,000 users across 600 offices across 6 countries. We're currently some Active Directory and some NT4.0. We have a project to migrate to a global AD design. This effort is part of the project. What I'm hoping for is that some of you, in large environments like ours, would be kind enough to share how you're handling DNS/DHCP and IP address management so we can get some perspective. Or if you have a recommendation for a methodology or a product, please share. Our network group's biggest gripe about Microsoft DNS and DHCP is no centralized reporting or management as well as lack of support for IP addresses that lie outside of the DHCP scopes.
