This was at the time when I was testing the TayLUG website on my home server and I was having port forwarding problems with the first router. The consequence of changing routers meant that I had to change the IP settings on the DNS server to properly point to the TayLUG website on my home server.<br>

When you use a different router that has a different MAC address than the IP/MAC address pair that is registered in the database does not match, then a new IP address is automatically issued. The good thing about this is that as long as your router holds good you are practically getting a static IP address which is great for running a home server operating personal (non-commercial) websites etc. Because I had only been with Virgin for just over a year, I was asking previously about how long people have had the same IP address hoping to get the reply "I have had the same IP address for 5 years" or whatever. <br>
