The Split DNS Architecture

Now that you have a good background on the special DNS techniques you can use, let's discuss a very common and fairly secure way to deploy DNS within your organization: using the split DNS architecture.

As I've briefly mentioned previously in this chapter, the split DNS architecture scenario consists of a set of internal nameservers that are used within the corporate computing environment in daily operations. There are also one or more nameservers facing externally to the Internet that outsiders use to connect to your corporation's electronic services, but that are separated from the internal nameservers for security purposes. Outsiders who query for information from your external nameservers won't be able to obtain information on your internal network structure and composition because the external nameserver is completely separate from the internal nameservers that hold this data. The external nameservers hold records only for externally facing servers and not for your entire internal domain. This technique is called the split DNS architecture because DNS information is split between the inside and the outside of an organization.
