It'll make it easier to see your history, track down errors, as well as recover from accidental GUI configuration overwrites! One other thing. While OSX's configuration tool might not let you put an underscore into a hostname, perhaps it'll let you put it into a subdomain? The routines that validate hostnames may be different from the ones that validate subdomains. I have no idea if this'll work, but it's worth experimenting with. You don't need to stop using Server Admin to manage the DNS, just go behind its back to add the records it can't handle.
This is possible because in OS X Server v Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Under the hood, OS X Server has a number of substantial changes; however, at first the Server app Server 3 appears to have had very few changes.

Reverse Zone: Zone that maps each name that IP addresses within the zone answer with. Reverse Zones are comprised of Reverse Mappings and each octal change in an IP scheme that has records mapped represents a new Reverse Zone.

You'll also learn about the various types of DNS issues, such as problems related to end users who misunderstand your DNS hierarchy and typographic problems within your DNS aliases.
A system administrator must be able to determine authoritatively where a DNS entry is being resolved. Like any resource, network resources are limited. When an organization signs on with an Internet service provider ISP , the ISP provides a limited number of IP addresses and a set bandwidth or maximum amount of network traffic allowed to the organization. To prevent extra charges, the organization must use the allocated addresses and bandwidth intelligently.
A company with unlimited resources could purchase an IP address for each computer on its network. However, this is inefficient because every company has intermittent network users, such as those who use portable computers and visitors. A more efficient approach is to purchase fewer IP addresses and allocate them dynamically as needed using a DHCP server.
Hosting an internal DNS server can reduce network demands and improve performance by locally caching hostname lookups. It can also be used to supplement and extend the domain name that the company purchased.
Another way to reduce bandwidth needs is to host a Software Update server. This allows updates to be served on the local network instead of each computer having to download the updates directly from Apple's website. This also enables a system administrator to make updates available only after they have been tested and qualified.
