When using Google for Work services, you might occasionally need to change your domain’s DNS settings. Here are some common terms you might encounter, along with how they apply to Google services. See also Domain name basics.

  • DNS
  • MX Record
  • TXT Record
  • CNAME Record
  • A Record
  • NS Record
  • Time To Live (TTL)
  • Uniform Resource Locator (URL)
  • Example DNS configuration



DNS stands for Domain Name System. This system is essentially the phone book of the Web that organizes and identifies domains. While a phone book translates a name like “Acme Pizza” into the correct phone number to call, the DNS translates a web address like “www.google.com” into the physical IP address—such as”″—of the computer hosting that site (in this case, the Google homepage).

When using Google for Work services, you periodically need to modify your DNS settings to set up various tools and services. You do this by changing various types of DNS records. You change your domain’s MX records, for example, to direct email for your Google Apps domain to Google’s mail servers.


Mail Exchange (MX) records direct a domain’s email to the servers hosting the domain’s user accounts. To set up Gmail with Google Apps, you need to point your MX records to Google mail servers. Multiple MX records can be defined for a domain, each with a different priority. If mail can’t be delivered using the highest priority record, the second priority record is used, and so on.

To configure your domain’s MX records to point to Google servers, see About MX records.

TXT Record

A TXT record is a DNS record that provides text information to sources outside your domain, that can be used for a number of arbitrary purposes. The record’s value can be either human- or machine-readable text. With Google for Work services, TXT records are used to verify domain ownership and to implement email security measures such as SPF, DKIM, andDMARC.

To add and modify TXT records for your domain, see About TXT records.

CNAME Record

A CNAME or Canonical Name record links an alias name to another true or canonical domain name. For instance,www.example.com might link to example.com. With Google for Work services, you use CNAME records to customize a Google Apps service address or the address of a web site built with Google Sites.

To add and modify CNAME records for your domain, see About CNAME records.

A Record

An A or Address record (also known as a host record) links a domain to the physical IP address of a computer hosting that domain’s services. With Google for Work services, you can add an A record to enable your “naked” domain address.

To add and modify A records for your domain, see About A records.

NS Record

Name server (NS) records determine which servers will communicate DNS information for a domain. Generally, you have primary and secondary name server records for your domain. When using Google for Work services, you may configure NS records that point to Google servers for DNS queries.

Time To Live (TTL)

The TTL is a value in a DNS record that determines the number of seconds before subsequent changes to the record go into effect. Each of your domain’s DNS records, such as an MX record, CNAME record, and so on, has a TTL value. A record’s current TTL determines how long it will take any change you make now to go into effect. Changes to a record that has a TTL of 86400 seconds, for example, will take up to 24 hours to go into effect.

Note that changing a record’s TTL affects how long it will take any subsequent change to happen. We recommend setting a TTL value of 3600, which tells servers across the Internet to check every hour for updates to the record. The shorter TTL will only take effect after the prior period expires. This means that next time you update the record, your change will take up to one hour to go into effect. To make subsequent changes happen even more quickly—for example, if you think you might want to quickly revert a change—you can set a shorter TTL, such as 300 seconds (5 minutes). Once the records are configured correctly, we recommend setting a TTL value of 86400, which tells servers across the Internet to check every 24 hours for updates to the record.

Uniform Resource Locator (URL)

A URL is the web address of a resource on the Internet. This is the address you type in a browser to visit a particular web site. For example, the URL of the Google Apps Help Center is http://support.google.com/a.

Example DNS configuration

Here are sample DNS settings for a domain used with Google for Work services.

Note that you don’t use the actual domain name in your DNS settings. Instead, you use the @ symbol to indicate the domain name.

Name / Host / Alias Record Type Priority Value / Answer / Destination
Blank or @ A NA
Blank or @ A NA
Blank or @ A NA
Blank or @ A NA
mail CNAME NA ghs.googlehosted.com.
Blank or @ TXT NA google-site-verification=6tTalLzrBXBO4Gy9700TAbpg2QTKzGYEuZ_Ls69jle8
Blank or @ TXT NA v=spf1 include:_spf.google.com ~all
www CNAME NA ghs.googlehosted.com.

Hosting Apache and WAMP Websites on Azure Cloud

After installing Apache, or a WAMP server such as WampDeveloper Pro, in a Windows VM on Azure Cloud, you’ll need to connect that VM to port 80 and also open internet access to Apache.

Create Endpoints for Port 80 and 443

Azure needs to have its “port endpoints” set up to be able to forward incoming port 80 and 443 traffic to the right VM (and the right port in the VM).

Create new endpoints from Public:80 to Private:80 (and the same for port 443). Don’t select/check-mark ‘Create load-balancing set’, nor ‘Enable direct server return’, unless you are running multiple VMs and want the traffic to be split between them for these ports.

Virtual Machine > Endpoint > Add endpoint > Next > name:http, protocol:tcp, public port:80, private port:80 > click Complete

How to Set Up Endpoints to a Virtual Machine

Configure Windows Firewall To Open Port 80 and 443

Windows Firewall blocks, by default, incoming port 80 (HTTP) and 443 (HTTPS) requests, for Protocol TCP and UDP. You’ll need to create Inbound Rules to open these ports.

Note that:

  • If IIS was installed previously, the existing port 80 and 443 rules might only be in effect for IIS. Delete them and create new rules for general port 80 and 443 use.
  • Check for any blocking rules automatically created for the Apache httpd.exe program, they will be named as such (Apache HTTP Server).
  • Every time you update/change Apache versions, the Windows Firewall will attempt to create a new blocking rule for it.

Clear Access Control List Rules

Select port 80 and 443 Endpoints and click ‘Manage ACL’. Delete any rules present (you do not need them for a publicly accessible website).


* It might take 10 minutes for endpoint changes to take effect in the system.

* Before installing or running Apache on Azure, make sure that IIS is uninstalled, or at least that its Service is stopped and its Startup Type changed from “Automatic” to “Manual” or “Disabled”. Apache and IIS are both configured (by default) to bind-to/listen-on ports 80 and 443 on all IPs, and unless they are bound to different IPs or on different ports, they will not be able to run at the same time (side-by-side).

One of the most common complaints about newer versions of Windows is the slow copying speed, especially when transferring lots of files over the network. If you want to speed up your copying or if you regularly transfer large amounts of data and have to stop the process to perform some other disk-intensive task, this program may be just what you need.

TeraCopy is designed to copy and move files at the maximum possible speed. It skips bad files during the copying process, and then displays them at the end of the transfer so that you can see which ones need attention. TeraCopy can automatically check the copied files for errors by calculating their CRC checksum values. It also provides a lot more information about the files being copied than its Windows counterpart. TeraCopy integrates with Windows Explorer’s right-click menu and can be set as the default copy handler.

  • Copy files fasterTeraCopy uses dynamically adjusted buffers to reduce the seek times. Asynchronous copying speeds up the file transfer between two physical hard drives.
  • Pause and resume file transfer activitiesPause the copy process at any time in order to free up system resources and continue with a single click.
  • Error recoveryIn case of a copy error, TeraCopy will try several times to recover and, in the worse case scenario, will simply skip the file, not terminating the entire transfer.
  • Interactive file listTeraCopy shows the failed file transfers and lets you fix the problem and recopy only the problem files.
  • Shell integrationTeraCopy can completely replace the Explorer copy and move functions, in turn enabling you to work with files as usual.
  • Full Unicode support.
  • Windows 8 x64 support.

PingInfoView (click to download)  is a small utility that allows you to easily ping multiple host names and IP addresses, and watch the result in one table. It automatically ping to all hosts every number of seconds that you specify, and displays the number of succeed and failed pings, as well as the average ping time. You can also save the ping result into text/html/xml file, or copy it to the clipboard.

SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise. SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol) and works fine with Windows 9x, ME, NT, 2000, 2003, XP, Vista and Windows 7. It works with Windows 64 bit too.
