About Website Domain Names

A website Domain Name is what a person enters in their Internet browser’s address bar to access a website. While real Internet addresses are made up of a complicated series of numbers, Domain names are the unique, human-readable Internet addresses of websites. If your website was a home, the domain name would be its address.

Why we Need Domain Names
The Internet is giant network of computers connected to each other through a global network. Each computer on this network can communicate with the other computers. For the computers to identify each other, each computer is assigned an IP Address. The IP address is a series of numbers that identify a particular computer on the internet. A typical IP address looks like this: "". Since numerical IP addresses can be quite difficult for people to remember, domain names were invented to solve this problem.

The Parts of a Website Domain Name
Domain names are made up of three parts: a top-level domain (sometimes called an extension or domain suffix), a domain name, and an optional Subdomain. The combination of the domain name and top-level domain is known as a "Root Domain".

Website Domain Name
  • Top Level Domain (TLD) - is the formal term for the suffix that appears at the end of a domain name. It is the first level of a domain's hierarchy. Some example of top-level domains include: ".com", ."net" and ".edu". While you are probably familiar with these TLDs, there are actually over 1,000 possible TLDs from which you can choose.

  • Domain Name - is the second level of a domain's hierarchy. This tends to be the most descriptive and readable portion of a root domain. Examples of domain names are:
No two different websites can have the same root domain. However, one website can have multiples root domains assigned. All the pages on the same website have the same root domain, and usually have their own domain name: "".
The above are both subdomains of their website's root domain. The most common subdomain is www (world wide web). It's also possible to omit the subdomain to access a website.
Buy a Domain Name
Every business, and everyone who needs to be found online, needs a website. If your business is not found online, it is irrelevant to those searching for your service or product offerings.

The first step is to buy a domain name (actually, the Root Domain). Anyone can buy a domain. To do so, you visit a domain name registrar, such as GoDaddy or Google Domains, key in the root domain you want to buy, and pay a fee. You buy a domain for a term, such as 1 to 10 years, and can renew your purchase at the end of the term (or even set up an auto-renewal). You may only buy a domain that is not already registered by another person or business.

Domain names put a friendly face on the hard-to-remember numeric IP addresses. Since your domain name is the name of your website, you want to make sure you get a good one. You will want to buy one that is catchy and short so that it's both easy for people to remember, and easy for people to type.

Stay Safe When Using Public WiFi

If you leave your home today, you’re bound to come across more free public WiFi hot spots than ever before. They can be great for getting work done, checking your email, managing your social media activity, and generally staying connected. However, public WiFi networks can also be a major security risk. Here’s what you need to know about using free public WiFi and how you can keep yourself safe.
Avoid Public Hotspots
Many WiFi hotspots are set up in public places by organizations that are willing to give you some free bandwidth in return for you supplying an email address or phone number. Never give up such personal information to get online. Also, it’s known that hackers can set up free WiFi networks to steal information from gullible people looking for free bandwidth. Instead, stick to the advertised WiFi networks that have been set up by a coffee shop, hotel, library, or whichever venue you’re in.

Stick to Using a Secure Connection
That little padlock that appears in your browser’s address bar when you are on a secure connection or website is especially important when you’re on public WiFi.

Think long and hard before doing anything important across an unsecured connection. That's because it’s going to be much easier for someone else on the same network to grab account access information or data that’s transferred when you use an unsecured connection.

When using mobile apps, you’re at the mercy of the app developer for its wireless security. Stick to apps from big, well-known names while on public WiFi to limit the risk. Although, that’s not a guarantee of security.

Turn WiFi Off When Not In Use
When you’re finished working online, turn on "airplane mode" or turn off WiFi on your wireless device. That’s not only a good security habit to get used to when you’re using unsecured networks. It will also reduce your battery usage since your device will not be powering the WiFi radio.

Keep Your Anti-Virus and Anti-Malware Up to Date
Always keep your anti-virus and anti-malware software up to date. This is even more important when you are online using unsecured WiFi networks. Some public WiFi networks have been known to send ads while you browse. Good and current protection software will keep you safe from this type of malvertising.

Use a VPN
Use a Virtual Private Network (VPN) when you are connecting to an unsecured WiFi network. A VPN routes your internet activity through a dedicated, encrypted server. When you have a VPN and you are online, you establish a secure connection to the VPN server, locking out anyone on the same network as you. All of your transferred data is encrypted between you and the VPN service provider.

VPN services, while extremely helpful, are not foolproof. Using a VPN can't protect you if you unwisely download ransomware or give up your data to a phishing attack. What a VPN can do is to protect you against snoopers on the same unsecured network looking to collect data for their later use.

Have Your Own Mobile Hotspot
The best protection from an unsecured WiFi network is not using one at all. Instead, use a mobile hot spot, or tether your device to your smartphone and use your wireless carrier’s data plan. Doing so gets you off the unsecured network. This is both safer for you, and you are not competing with others for public bandwidth. Make sure you have a data plan for your hot spot device that will support your online use to avoid data overage charges.

No matter what steps you take to try and stay secure, remember that public networks are inherently more exposed and unsecure than the ones at your home and place of work. If you’ve got banking or online purchasing to do, avoid typing in passwords, usernames, credit card details or anything else that could be of use to someone else who might be scanning the same network. Don’t be afraid to get connected while you’re in public. Just make sure you are careful when you do.
