Where Is My DNS Hosted?

From time to time, you’ll have to make changes to your DNS records. For example, if you change IP addresses, your DNS A records will change. You’ll also change DNS if you want to add SPF records to help email authentication. For these changes to work properly, it’s vital to know where DNS is hosted.

DNS is always hosted at your domain’s authoritative nameservers. Your authoritative nameservers, and therefore your DNS, can be in three places:

  • Liquid Web’s nameservers
    • ns.liquidweb.com
    • ns1.liquidweb.com
    • ns.sourcedns.com
    • ns1.sourcedns.com
  • Your private nameservers on your server or another server you control
    • Ex.: ns.mysite.com
  • Where you registered your domain name
    • Ex.: Enom, GoDaddy, Namecheap, etc.

If you are using Liquid Web’s nameservers, you can update your DNS records in your Liquid Web account interface. If you use private nameservers on your server or another server, you can update DNS records in the control panel for your server (most likely WHM or Plesk, sometimes cPanel for SPF records). If your nameservers are where you registered your domain name, you’ll need to log into your account at that registrar and edit DNS there.

Either way you check your domains authoritative DNS you should always remember, if you don’t update DNS in the right place it wont take effect. This could mean your websites won’t load properly and can cause unnecessary downtime.

Discovering Where DNS Is Hosted – Web

If you aren’t comfortable using your terminal program to look up WHOIS information, use an online WHOIS checking tool.

Discovering Where DNS Is Hosted – CLI

You can easily find out where your DNS records are hosted using your server’s WHOIS entries.

  1. Launch your terminal program. Every operating system (Windows, Mac, and Linux) has a terminal program: use your computer’s search function to look for “terminal,” then open the terminal program you find.
  2. In the terminal window, type:
    whois mysite.com
    and press Enter. Be sure to replace “mysite.com” with your site’s domain.
  3. You’ll start seeing a lot of information about your domain, including where it is registered and the nameservers you’re using.
    Domain Name: LIQUIDWEB.COM
    Registrar: NETWORK SOLUTIONS, LLC.
    Sponsoring Registrar IANA ID: 2
    Whois Server: whois.networksolutions.com
    Referral URL: http://networksolutions.com
    Name Server: NS.LIQUIDWEB.COM
    Name Server: NS1.LIQUIDWEB.COM
    Status: clientTransferProhibited https://icann.org/epp#clientTransferProhibited
    Updated Date: 04-aug-2016
    Creation Date: 05-aug-1997
    Expiration Date: 04-aug-2026
  4. Look specifically at the Name Server listing. In this example, you’ll see liquidweb.com uses Liquid Web’s nameservers. You might also see your own server listed as the nameserver (ns.mysite.com) or a domain registrar listed as the nameserver. This information tells you where you will be editing your DNS records:
    • If you use Liquid Web nameservers: edit your DNS records in your Liquid Web account.
    • If you use private nameservers: edit your DNS by logging into cPanel and searching for “Edit DNS Zone.”
    • If you use a different registrar’s nameservers: edit your DNS records by logging into your account at your registrar.

7 Extremely Useful Linux Commands for Beginners

#1: ls : What’s in this directory?

The command ls stands for list directory contents. And, cleverly, it will do just that: list a directory’s contents! Using it with -F will give a list of the directories contents, and denote items that are other directories with a trailing /.

ls -F

On my server returns:

allthethings.txt important.doc Indominus/ Misc/ probs.xls Red Wings/ Spreadsheets/ Work/

In the above case, allthethings.txt, garbage.file, important.doc, and probs.xls are files, and Indominus, Misc, Red Wings, Spreadsheets, and Work, each with the trailing /, are directories!

There are many other options, or switches, such as -F that can be used with ls for improved results. For example:

ls -lFa

Returns:

dr-xr-x---. 10 root root 4096 Apr 17 12:01 .
drwxr-xr-x. 19 root root 4096 Apr 14 12:45 ..
-rw-r--r-- 1 root root 0 Apr 17 12:00 allthethings.txt
-rw------- 1 root root 483 Apr 14 12:45 .bash_history
-rw-r--r--. 1 root root 18 Dec 28 2013 .bash_logout
-rw-r--r--. 1 root root 176 Dec 28 2013 .bash_profile
-rw-r--r--. 1 root root 361 Jan 1 01:24 .bashrc
drwxr-xr-x 3 root root 4096 Jan 1 01:25 .cache/
drwxr-xr-x 3 root root 4096 Jan 1 01:25 .config/
-rw-r--r--. 1 root root 100 Dec 28 2013 .cshrc
-rw-r--r-- 1 root root 0 Apr 17 12:01 garbage.file
-rw-r--r-- 1 root root 0 Apr 17 11:58 important.doc
drwxr-xr-x 2 root root 4096 Apr 17 11:59 Indominus/
drwxr-xr-x 2 root root 4096 Apr 17 11:57 Misc/
-rw------- 1 root root 42 Apr 14 12:44 .my.cnf
-rw-r--r-- 1 root root 0 Apr 17 12:00 probs.xls
drwxr-xr-x 2 root root 4096 Apr 17 11:57 Red Wings/
-rw------- 1 root root 1024 Jan 1 01:22 .rnd
drwxr-xr-x 2 root root 4096 Apr 17 11:56 Spreadsheets/
drw------- 2 root root 4096 Apr 14 12:42 .ssh/
-rw-r--r--. 1 root root 129 Dec 28 2013 .tcshrc
drwxr-xr-x 2 root root 4096 Apr 17 11:57 Work/

In the above case two switches are added: -l and -a. The -l uses the long listing format, and the -a switch lists all of the files, including hidden files.

Each column contains an important bit of information:

Column | Information | Example

  • 1 | Permissions | drwxr-xr-x
  • 2 | # of Hard Links | 2
  • 3 | User That Owns File or Directory | root
  • 4 | Group for File or Directory | root
  • 5 | File Size | 4096
  • 6 | Timestamp | Apr 17 11:59
  • 7 | Filename | Indominus/
