the domain
The internet is full of resources that are stored across servers in various locations and accessible through Domain Names. These Domains are mapped to the location of data storage through the means of IP Addresses and this mapping is accomplished using a system of creating Resource Records called Domain Name System (DNS). The DNS for a Domain defines the location of the resource, relevant to the particular Domain, and is retrieved as the DNS resolution of the Domain happens. The DNS resolution starts when a user requests for a Domain at the browser and ends with either the web page on screen or a relevant error message.
Most Domain Registration providers offer DNS Management as a part of the Domain Management control panel, however, this used to be a chargeable service until not too long ago. Slowly the providers have realized that DNS Management service, is an integral part of the Domain and thus has to be provided without a cost. Now, while it may look that DNS Management is necessarily a part of your Domain Registration, it is not necessarily that way. In fact, it is always suggested that the DNS Management should be configured with your hosting provider. This is since all of your resources, for the Domain Name, is with the Hosting provider and therefore it is advisable that the DNS Management be done at the Hosting servers.
While there are quite a few DNS Management Records that can be added for a Domain Name, the most common are listed as below:
Address (A) Record:
This is the most basic of records and points a Domain to an IP Address. This record is used if the DNS Management provider and the Hosting provider for a Domain Name are 2 different companies.
Canonical Name (CNAME) Record:
These are records that are used as Domain aliases for multiple Domains. Like abc.in can be CNAME to abc.com, which will display the content of “http://www.abc.com” when a user requests for “http://www.abc.in”.
Mail Exchanger (MX) Records:
The MX record is useful for designating the servers that handle emails for a said Domain Name. So if a user is sending an email to “abc@123.com”, then the MX record will define the IP Address for the servers that is handling emails for 123.com, and the email process will proceed.
Besides the above, there are following DNS resource records can be added for a Domain Name:
1. NameServer Records
2. Text (TXT) Records
3. Service (SRV) records
4. Start Of Authority (SOA) Records
While DNS Management can be seen as a bunch of a few records that associate Domain Names to IP Addresses, it is the back bone of the internet and is the core requirement for the smooth functioning of all internet services.
Every website on the Internet contains a domain, which is one of the main elements that make up a DNS (Domain Name System) address. A domain is a significant part of a URL (Uniform Resource Locator) because it locates any entity on the web. There is more than one domain name, and they are separated into diverse categories, which are represented by a suffix such as .com, .net, .org, .edu, .ca, .uk, .fr, and so on.
Just like websites, email addresses also feature domains, and the domain of an address can reveal information about the e-mail sender. What type of information? Sometimes a domain suffix can tell you the country the email address is from, for instance, .us (United States), .ca (Canada), .fr (France), .uk (United Kingdom) etc.
On the other hand, common U.S. domain suffixes, such as .com (Commercial), .net (Network), .edu (Educational), .gov (Government), etc. are typically used to represent a type of industry, institution, and so on. In example, many company websites use the domain suffix .com. However, with the exception of .gov, .edu, and .mil, anyone can register any domain, regardless if their intent is to match the definition of the suffix they choose.
What this means is that spammers can email you with a false identity from a popular company (I.E. eBay) and use a fake, but similar, domain to try and trick you into downloading their malicious attachments, or have you follow the link provided in their email to scam you out of money or personal information.
Therefore, you need to pay close attention to the domains of electronic mail messages you don’t recognize. For instance, if you receive an e-mail from a customer service representative from eBay and the domain used in the address is .net, right away you will know that this is a phoney message, because eBay’s domain is .com.
Thus, if you receive “important”, “urgent” or too-good-to-be-true emails from a company you may or may not do business with, make sure you don’t click on any link or attachment in the message, and investigate the true domain online by looking up the name of the company in a search engine.
Once you have verified the domain, you should then proceed to find out who the email is from by investigating the email message headers, and running a reverse email lookup to see what other information you can find.
Suppose the domain name you have chosen has already been taken. Now what will you do? You may either keep searching for a name that is not yet taken, or contact the owner of the domain name and want to purchase it. Before negotiating with the owner, visit the domain name you want and check if it is active. Some owners prefer to sell the name if they are not using it at all. Some others buy domain names for selling them for a large price in the future. Be careful not to overpay for your domain name.
You can obtain the contact information for domain name owners from the domain name research sites.
Network Solutions, a foundational registrar for .com and .net, offers a simple WhoIs query function that may suffice. It, however, is limited to searching by the exact domain name or by NIC handle, customarily the owner’s initials followed by a number. Register.com has a WhoIs search function on most of its pages that check a domain name with or without specifying the extension simultaneously across a range of popular extensions and some country codes. In addition, it suggests some available name variants in case your searched name has already been taken.
Allwhois.com, BetterWhois.com, TrueWhois, Whois Source and WhoIsQuery.com are also useful as each of them can access various registrars’ WhoIs databases that contain many country domain registrars. These sites also have a variety of unique search capabilities, and sometimes can provide a fuller and more accurate response for exact matches of partial or full domain names.
AMNESI can reveal a range of similar names that can be utilized for identifying misspelled or similar versions of a name. Whois.net is capable of searching a database of deleted names using your name fragments. That can be extremely useful in discovering what someone else thought was a worthwhile name previously but which is now available again.
