Now, let us take sometime to understand some conventional DNS settings terminology which could be required of you to employ a separate host for email services (including Google Business apps) or changing your blog host as well as occupying your email address extension with your domain name.

1. DNS

DNS means Domain Name System. This acronym represents the IP (Internet Protocol) address your blog uses for hosting. A server with different hosted blogs shares one IP address for all its occupants. It is possible to find out your IP address by looking it up online.  IP addressees are presented as 1o digits preferably in the following format :##.###.##.###.


NS Record means Name Server Record. You could be recommended to change your name servers with your domain registrar when you want to change your email host or blog host. This simply means you need to as well change your Name Server (NS ) record.

The proper web location when your site migrates is pretty important. If you therefore change your host, your IP addresses changes as well with the server as this would identify the DNS information for your site. If you don’t change the primary and secondary NS records, then browsers would be referred to your former server whose tenancy you have exhausted.

If this is not done, it would be impossible for your URL to lead to your blog on a browser. This you could do by correlating NS records to your new server or your blog. NS records are alphanumeric and typically formatted similar to

This couples DNS records with text. It is very versatile especially for web developers, as a blogger, it could serve domain verification purposes when hosting through an external domain registrar or blog host as the case might be.

7. Time to Live (TTL)

Every DNS record presents a correlating TTL value . This figure interacts with servers attempting to access your blog and communicates to them how regularly to check your blog for updates to your DNS records. As a popular convention, setting the TTL value to 3600 is bright! This setting helps servers to access your records for corrections once every hour. You can vary up down the TTL value as preferred to execute changes with the needed pace

8. DNS Propagation

This the time lapse required for adjusted DNS records variations to be presented live across the internet. Basically, this takes 24 to 48 hours to fully distribute across the internet and the world. This means visitors around the world could find it hard to reach site at your new host until the new DNS settings have been totally dispersed.
