How do you know that you are dealing with the right person or rather the right web site. Well, someone has taken great length (if they are serious) to ensure that the web site owners are who they claim to be. This someone, you have to implicitly trust: you have his/her certificate loaded in your browser (a root Certificate). A certificate, contains information about the owner of the certificate, like e-mail address, owner's name, certificate usage, duration of validity, resource location or Distinguished Name (DN) which includes the Common Name (CN) (web site address or e-mail address depending of the usage) and the certificate ID of the person who certifies (signs) this information.
The signup button is just on the top left corner of the website. After completing the formalities and registering you will be provided a customer code. In future, you need to sign in using this customer code and your password only. Once this is done, just type-in your desired domain name and press enter. If it is available, then well and good; if it’s not then you’ll have to find another combination of your domain name and the suffixes like .org, .com, .net etc. Once that is done, you will have to check out from the location towards the billing area. Now the obvious question which comes to everybody’s mind right now is what are Zone files and Zone records. When you buy a domain name from any vendor, be it godaddy or google; Every single domain will have a zone file and each zone file will have zone records. Godaddy supports upto 20 zone records. Now these zone records contains the domain name server information which links the particular domain name (your Domain name) to the specific IP address. Regarding Zone records, the above discussed CNAME is an alias for a host, using it you can have more than one DNS name for a host. If you talk about ‘A Host’ it maps the IP address to the host name.
There are times in huge websites when certain resources cannot load properly, for example images or videos. So what does the website developer do when he’she is confronted with such a situation. He creates a backup of the resources and instructs the website to fetch the resources from the backup if the original returns nothing. Similarly if you have a missing files host and you are trying to fetch www.blogname.com/image.jpg and you do not get the image you can use the host and get the files from www3.blogname.com/image.jpg. But for blogger users this might come as a shock to some that google’s blogger has discontinued the use of File Transfer Protocol (FTP) on its websites after the first of may 2010.
