Default gateway, what is it?
We have now covered Ip addresses and Subnet mask.
Now the third thing to be explained is default gateway.
This is generally the ip address of the router or the computer that does the initial connection to the internet. Most of the default IP adresses are something like this: 10.0.0.2 or 192.168.1.1 or 192.168.1.254. If your Router has one of those IP addresses, generally found in the manual of the router.
The same goes for the DNS address. This can be the same as the router itself, and then the router will do the actual proccess of DNS. Dns server addresses look like IP addresses.
DNS (Domain Name Service) is basically a server that has a long list of IP addresses that link up to website addresses. So www.gitui.com will be translated into 72.167.96.53. Without DNS, the internet would be very slow and difficult to surf.
More on DNS. (a bit later)
Domains and how hosting works
So you’ve got a company and you have just started. In today’s world, before you can really get going you will need email addresses, maybe a website. Well first of you before you even start, you will need a domain name.
This could be anything, most preferably you will want it to be your company name. A domain name in my case would be “gitui.com“. So once you have a domain name, you can then get yourself an email address. such as: director@company.com or whatever you want it to be, within the domain “company.com”
A domain is an online name registered to a person for a period of about a year, maybe 2. They are quite cheap, so everyone can have a domain name on the internet.
A website, could then only come later, Much later if you want.
Once the website is designed and ready to launch, you will then have to upload it to the server where your domain is kept. Basically a server somewhere out there that controls your emails and traffic. It also controls you DNS, website, and much more. (I will get to explaining that later.) Once you have uploaded the website to the server using a protocol named FTP, (File Transfer Protocol) your website is almost ready to go. If it is a good company you are doing your hosting through, then they would have set up your DNS already. If this is not done, you will need to ask them to do so.
That is a very basic break down of how hosting and a domains work. IF you have any questions, ask.
Over time I will be explaining more and more. But for now, ask and I will try and answer you as best as possible.
