If you follow DevOps trends, you have likely heard of infrastructure as code. Tangibly, infrastructure as code means having things like your network configuration, server attributes, access control, etc. in a machine-readable format. This code then:

Serves as the source of truth for what the infrastructure should look like
Can be used to recreate the infrastructure from scratch
Is under version control
Is modified by pull requests
DNS is a major piece of shared infrastructure at the Technology Transformation Services (TTS, which 18F is part of), which made it a prime candidate for infrastructure as code. Of the many benefits, doing DNS changes through pull requests rather than tickets brought turnaround time down from multiple days to under ten minutes.
