By running a caching DNS server it will cache DNS locally so sites you visit often will not have to make a DNS query until the DNS record has expired.
Another great benefit to running a internal DNS server is you can just type the name of a device like server, firewall, printer, basement-pc, or whatever you want to call your network devices. Before we begin I am assuming you have an Ubuntu server running and configured with a static IP address.
You will need to be at the console of your Ubuntu server or have SSH setup and connected to your soon to be bind9 DNS server.
At this time .rocks is not a top level domain on the internet, but it does not mean it won't be tommorow. When looking at our IP address the part we care about is the first three sets of octets (numbers). Now that we have defined what zone files to load when Bind starts, we need to create these files.
The three most common types of DNS records are Address (A Record), Canonical Name (CNAME), and Mail Exchanger (MX). Note: Leave the 0 off the front, so on numbers under ten like 01 would be 1 instead of 01 .

If you are looking for some more details on DNS and Bind O'Reilly has a really great book that I recommend. I have given a few public IP addresses to some of my customer and they are running mail servers on them.
Today I've checked my SPF is valid on some of the sites and invalid on some of the sites I've tested. OK so I'm having a hard time configuring reverse DNS for my website protected by cloudflare.
I run a VPS on a Windows Server 2008 machine, and since I got it in January 2015 everything has been running fine, the server has IIS, DNS, and uses Mailenable for email exchange.
Why does Uncle Bob suggest that coding standards shouldn't be written down if you can avoid it? Is there any point in unit testing a client service that simply passes through data from the server? If async-await doesn't create any additional threads, then how does it make applications responsive? Is it possible to combine two separate transactions into one transaction by only using their signatures?

There is no need to remember the IP addresses of the devices when you can just type the defined name.
If you want to use something else just make sure you replace in the following steps with your internal domain name. We will also use CNAME records to map the name server01 to ubuntu-server and server02 to ubuntu-server2.
I have noticed a huge improvement with my satellite internet connection just by running a local DNS caching server.
So in this example we could use linux.test and not have to worry about that domain every being a real domain on the internet. In a later tutorial we will look at setting up DHCP to update our DNS records but for now we will just setup a basic DNS server. You can manually set it on each machine or edit your DHCP server to hand this out with the IP addresses.
