When i was a really a newbie,I went to install and setup the computer network myself (instead of getting a package ADSL modem from my ISP which cost a lot more and without any built in router), the computer shop tech assistant told me that i at least need a ADSL with a router build in and a hub so that all the computers can go online together. But now after reading certain posts ( i cannot remember), i noticed that i don't really need a router to do the same stuff. Anyone mind clarify me on this?
P.S i also noticed that for a certain huge housing area, they all share the same DNS server address provided by the ISP.Anyway, i am just curious as why the DNS server is the same?By the way , my IP address is dynamic because I check with ipconfig /all and the IP changes all the time.
Thanks in advance.
