Why should I get a static IP address?
There are many benefits to be gained from using a fixed IP address. These include:
* Remote access - With a static IP address you can access your PC no matter where you are in the world. Using programs such as Remote Administrator and PC Anywhere you can log into your work or home PC no matter where you are.
* Running your own website - Installing web server software on your PC allows you to set up your own website and can save you money if you need one for your business, or just want one for personal use. There are plenty of free programs available on the internet but make sure you do your research and check customer reviews before installing anything.
* Emails direct to your PC - Using a static IP address also lets you get rid of your Hotmail or Yahoo! account and set up your own email address with your choice of domain name. Again, this is especially useful if you run a small business. You need to install separate mail server software to do this, but there are free ones available.
* Running an FTP server - File Transfer Protocol (FTP) is an efficient and reliable way to transfer data from one computer to another. Again, specific software must be installed in order for you to set up an FTP site, but this is easy to do and free software is available. You might want to use an FTP site to share files, such as pictures, with your friends and family, or you might use it to enhance your business. Either way, once you’ve set up the site, clients or friends just need to log in to access, edit or uploads files.
* Running a game server - For all those online gaming addicts, having a static IP address means that you can take your gaming to the next level. Most PC games have an option for operating your own server, allowing you to select your own settings and regulate who you let into your game - so you and your friends could have a private game of Battlefield.
* Less downtime - Each time a dynamic IP address refreshes you run the risk of downtime from the server. While this is usually only for a very short time, it can wreak havoc on your gaming. Having a static address eliminates this risk.
Are there any disadvantages?
While the benefits do outweigh the problems of having a static IP address, a few issues should be noted:
* Hacker risk - Having a constant IP address means that once hackers have your number they can keep on attacking. Dynamic addresses change all the time making it more difficult to get into your PC. However, using a router and firewall will help to block access to your computer.
* Keeping your connection running - If you’re using your PC as a server to run a website, receive emails, run an FTP site or a gaming server then you need to make sure that it’s on all the time. Any time it isn’t connected to the internet will result in lost access to sites run from your server.
* FTP security - If your clients are downloading sensitive or confidential files from your FTP site, you need to consider the security issues posed as files and passwords are in clear text and easier hack.
