New layout & Updates

Posted in Latest news on March 24th, 2011 by yokke


As you might have noticed, I changed the layout of the blog. The main reason is very simple, Internet Explorer messed up. . . .

I don’t really know or this layout is good so any feedback is welcome.


The next couple of days you may notice some updates. I’m going to make some new categories on the website. These categories will go about my portfolio at the end of my graduating year. That’s also the reason why I’m  making those categories in Dutch.

Access your server from the outside world with a dynamic IP-addres

Difference between a static and a dynamic IP

An IP address is used to communicate between computers. When a server has a static IP this will never change unless someone decides to. This IP is manually entered in the computer or server.An example of who uses a static IP is a web server. Every domain name has a web server, every public web server has an static IP.  For example has the static IP this IP will never change unless Google decides to move the web server to an other location. Because it isn’t possible to learn every IP-address on the internet we invented DNS (Domain Name System). How DNS works I’ll explain in one of my following tutorials for now just remember that DNS will resolve a domain name to the IP of the server.

What are the advantages and disadvantages of a static IP distribution


  • You can learn the IP
  • You can host a web server


  • You need to configure an IP on each computer
  • You need to remember which IP-addresses are already used in your network

What are the advantages and disadvantages of Dynamic IP distribution

90% of the computers use a dynamic IP. This IP is distributed by a DHCP server.


  • You don’t have to configure an IP manually
  • You can use Dynamic Domain Named Services to find your computer


  • You need an DHCP server
  • You need to configure reserved addresses for printers etc
  • You don’t now which IP belongs to which computer unless you use DNS

So how do I solve my problem when my ISP gives me a dynamic IP and I want to contact my personal server from the world wide web?

Well, I’m going to explain this for my own ISP (also the router settings, this can be different on your router).
