Manually Setting Dns Mac Os X Server This document is part of of Apple OS X 10.10.x Network Configuration, and describes on whether you choose to use DHCP, BootP, or manual configuration. (So does BootP, an older service, but it provides less information to your Mac.) Make sure that the DNS Servers list is empty or contains only IP addresses. The DNS manual entry fixed it all. Does the 'dns' field really need to filled in? On my mac, its just optional. Manually entering DNS number on iPhone More. When you add a permanent entry to the local DNS cache on your PC, it will always override the information provided by the nameserver. If a nameserver gives the wrong address for a domain or provides no information at all, you can still access the domain if it’s listed in the local Hosts file. Manually Override DNS DNS on Mac. Mac is the same as the above linux example. Simply edit the hosts file under /etc/hosts and add in the entries as needed. So again, you could enter something such as: 172.10.1.5 www.anydomain.com Manually Override DNS Using IPV6. You don’t always have to use a standard IPV4 as the IP address.
(To check, see How to Find Your Mac's IP Address.) That's not a problem for the majority of users - most people don't care whether their IP addresses changes or not. But dynamic IP addresses won't work for certain tasks like port forwarding, dynamic DNS, or client-to-client file sharing on the local network. I have tried using the Network pane of System Preferences to set the involved ethernet port to 'configure: Using DHCP with manual address' and setting an IP address in the range of the IP addresses used by the AEBS - but I get no internet access that way; the Mac never gets the Subnet mask and router IP address fields filled in after clicking.
First off, let me explain what a DNS Entry is in order for us to understand why we would need to override it. Basically a DNS entry is a record or entry that tells us what ip address is of a domain will point to. Such as an example (not actual) IP of 66.12.23.124 could point to a domain such as www.example.com.
Say perhaps we are updating a DNS entry and as the nature of DNS would have it, sometimes it will take up to 48 hours for the DNS to propagate through the Internet. Or perhaps we don’t want to update a DNS record which could affect everyone but rather just change a record for ourselves, locally. In these case, we can manually override the DNS change which will only reflect on our local machine. Below I will show you how to achieve this on Windows, Linux and Mac.
Manually Override DNS on Windows
Open up the hosts file located under “C:WindowsSystem32etcdrivers“. In there you will see the IP address in the left column and a space separated list of domains to the right. The below example will set the 3 domains of www.example.com, anotherdomain.example.com and lastdomain.com to the IP address of 10.0.0.1.
Manually Override DNS on Linux
vi the hosts file which is located under /etc/hosts. Add in a line below the last entry in the same fashion as you would for windows. For example if you wanted to change the ip address for the domain www.example.com to point to 192.168.0.20 you would enter:
Manually Override DNS DNS on Mac
Mac is the same as the above linux example. Simply edit the hosts file under /etc/hosts and add in the entries as needed. So again, you could enter something such as:
Manually Override DNS Using IPV6
You don’t always have to use a standard IPV4 as the IP address. You can also use IPV6 and enter it into any of the hosts files like so:
And that is all there is in Manually Override DNS in windows, linux and mac.
When you add a permanent entry to the local DNS cache on your PC, it will always override the information provided by the nameserver. If a nameserver gives the wrong address for a domain or provides no information at all, you can still access the domain if it’s listed in the local Hosts file.
It could also improve lookup performance. If you frequently access a particular server, and you know its IP address isn’t likely to change anytime soon, you can add a local entry to eliminate the initial delay as Windows looks it up. For example, add an entry for your personal website or corporate mail server, so that those DNS lookups aren’t needed.
Also, if you frequently access a remote server without a domain name (rather than only by its IP address), you can configure a custom domain name, to be used as a kind of “shortcut” to the server. So, instead of typing MySQLServer.CorporateDomain.net, you could just type SQL1 into your browser and connect to that server.
Edit Local HOSTS File
To edit your local DNS lookup file, go to the following folder: C:WindowsSystem32Driversetc. Note: I am assuming that you have Windows installed in drive C, otherwise change it to your own Windows drive.
Note that there is a special way you have to open the hosts file in order to be able to edit it. Read my previous post on how to edit the hosts file here first. Once open, add an entry at the bottom with two pieces of information: the IP address and the customized domain name. The IP address and the domain name entry should be separated by a single space or a tab. In the example below, I entered an IP address for my Western Digital NAS and I gave it a name of NAS:
Now when I type http://NAS into my browser window, it brings me straight to the web portal for my NAS. Note that you cannot just type the word NAS into the address bar for most browsers because, by default, it will perform a search using your default search engine. You need to have the HTTP in the front so that the browser understands you are trying to resolve a DNS address. It will then check the HOSTS file first.
As for making sites a tiny bit faster, you can add an entry like I did here for my website:
Since my web server IP address isn’t changing anytime soon, I can just add it to the HOSTS file and Windows will never need to do a DNS lookup for that domain.

What’s more fun is using the hosts file to manipulate DNS entries. For example, I could put a different IP address, but leave helpdeskgeek.com as the host name. Now when I type helpdeskgeek.com on that computer, it would take me to whichever site is hosted on that IP address!
