What is the name of the unique number that all devices on an IP network use to identify themselves and their location on the network?

The internal ip address (usually looking something like this 192.168.x.xxx) is the unique number that devices use to identify themselves on a network

The external ip address is the ip address that is broadcasted to every website you visit and every person you email. It is unique (opposed to an internal ip address) it is also the only type of ip address that can approximately located.

So to answer your question, an internal ip address is a unique number that all devices on an IP network use to identify themselves, but it is only unique on your network.

Pros and cons of cat6 cabeling?

Cat6 cable is very similar to Cat5e cable. It is, simply put, just held to a stricter standard than Cat5e cable. Since Cat6 is made to a higher standard than Cat5e it will support higher speed transfers. Cat5e cable can be used for networks up to a 1Gbps speed while Cat6 is currently rated for up to 10Gbps speed. Cat7 takes this even further and supports 40Gbps. For normal usage on networks up to 1Gbps and no run being longer than 100 meters, Cat5e is completely sufficient for the network. To ensure forwards compatibility it may be worthwhile to install Cat6 cable while you're at it so you don't hit a speed cap in your network down the road.

It's hard to speculate about the problem, but DHCP has three methods how IP might be assigned to he machine. Manual (You set which machine which IP has), Dynamic (When you machine asks for IP and it gets from free IP pool and it can ask every time the same IP, extend it's usage. In this case you might loose your IP and you will get different one.) and Automatic (DHCP sets IP to machine permanently, it uses MAC-IP relation. Changing the MAC, might change your IP).
