Building a Dynamic DNS Server for Your Enterprise?

Biff98 asks: "We manage thousands of hostnames for field gear with DynDNS.org. It's always been our intention of configuring our own DDNS server and bring it in-house. Given the recent DynDNS outage due to a DDOS attack, resulting in the inability to resolve names for multiple days, there has been 'encouragement' from management to move forward on bringing DDNS in-house. Here's the problem: I can't find any easy-to-use, scalable software to accomplish this task! BIND doesn't scale well, and I don't consider MintDNS an option due to the required platform (Windows Server w/ AD & IIS). Has anyone out there solved this problem before?"

PowerDNS

Why don't you give PowerDNS a try?

It has an authoritive component and a recursive one, both work extremely well and are in use by some big companies, as well as the Wikipedia and the .TK TLD.
As for flexibility: PowerDNS uses backends to retrieve its zone data, so you can use one that's already available (MySQL, BIND zone files, SQLite, ODBC, etc.) or write one yourself.

Oh and it's opensource :)

I used it when I was running an ISP a few years ago. Used a replicated MySQL backend behind three authoritative servers. Also used dnscache for recursors in front of all the customers.

All your zone data is stored in DB tables, so it's easy to hack together a frontend, or integrate with CRM or whatever. I wish Rails had existed back then for all the CRUD that I wrote by hand. :/
