What’s easier to remember? www.Inspire.net.nz or 220.127.116.11? A name, of course.
Mapping domain names to IP addresses is one of the functions of the DNS. Another job for the DNS includes telling mail servers where to deliver email.
A data cap is the total amount of internet usage available on your plan. Watching videos on Youtube or TV on demand, playing games, general browsing etc. will all use your data.
Every device on the internet has a numerical address called an IP address. Since remembering numbers is a lot harder than remembering names, a Domain name is used to point a name to the IP address of the service you want to use. You can use a Domain Name for websites, email and many other services. For example you could type 18.104.22.168 into your internet browser and get our website, but www.google.com is much easier.
The term firewall is slightly misleading, because it is actually an IP network traffic management tool. That’s a bit of a mouthful, but describes more accurately what a firewall does: a good one will give you control over what comes in and what goes out to and from your computer (or network). In this day and age, a good firewall is a necessity. Not all firewalls are created equal, however.
For transferring files between computers, you will often see “ftp” being used. Although most Web browsers understand ftp, there are many specialised programs for the protocol which offer greater control over the transfer.
The language used by Web browsers to fetch HTML and other content from Web servers anywhere around the world is called HTTP. You can specify this when you type in the URL in your Web browser, e.g. http://www.Inspire.net.nz.
What started out as a research project in the United States to create a network of computers with the ability to survive nuclear strikes that took out parts of it has now become a truly global medium linking people in a manner nobody foresaw.
When you connect to the Internet, your computer becomes a node on it. This is an important thing to remember: connecting to the Internet is not the same as making a telephone call, or watching broadcast television. Your computer will send as well as receive data, and thus is visible to other Internet users.
This means you need to pay attention to security for your computer, because there are unfortunately rogues – spammers, scammers and crackers – who are quick to abuse unprotected Internet-connected computers. Make sure your computer software is up-to-date and consider investing in a firewall.
IP is one of many protocols on the Internet. Its role is to deliver data in packets to and from Internet-connected computers, which are identified with an IP address. Splitting the data up in packets allows them to take many different routes to computers. This is an intentional design feature of the Internet, which allows it to survive partial large-scale network outages. Unfortunately, the free routing across all hosts on the Internet is no longer done, as the networks have become commercialised and charge for traffic.
Currently, the Internet is built around IP version 4, but the more feature-rich IP version 6 is starting to appear on experimental networks.
A unique address consisting of four dot-separated groups of numbers, each of which range from 0 to 255, used to identify computers on the internet. For instance, our main Web server can be found at the 22.214.171.124 IP address.
The above addresses are for IP version 4. IP version 6 will have much longer, and thus many more addresses are available.
Once you reach data cap we will slow your internet connection down until your current billing month ends. We limit your speed to 128Kbit.
A bit is a unit used to measure digital information. When we refer to a Mbit or Kbit we generally mean how many bits of information per second your connection can transfer. A Kbit is 1000 bits and an Mbit is 1000 Kbits. For example, a 3 minute song in mp3 format would take roughly 25 seconds to download on a 1 Mbit connection.
If you want to keep your connection going at full speed once you have gone over your data cap, you can select a Pay Over Cap plan where you pay $10 per 10Gbyte block (or part thereof) used over your data cap.
To make sure IP packets are delivered to computers on the Internet even if they arrive out of order, TCP is used. Hence, we talk about TCP/IP.
A simpler protocol for network communications than TCP, UDP is often used for timing-sensitive applications that only shift small amounts of data, like online games and DNS.
Ultra Fast Broadband is the term used to describe the new fibre optic network which is being installed throughout New Zealand. This network will eventually replace most of the existing copper based services and not only be used for internet but also TV, medical monitoring and many other services.
