Summary
With our discussion on DNS drawing to a close, you should now have the tools available to build a basic internal DNS server and a standard DNS server facing the internet. You should also have the basic tools to start securing these services by editing the various configuration files for the Linux bind or named service.
In addition, you should have some familiarity with troubleshooting various DNS services, using tools such as dig, kdig, curl, and nmap.
In our next chapter, we'll continue on with a discussion on DHCP, which—as we've seen in this chapter—is definitely separate, but still can be related to DNS.
