Solve : Router shows unauthorized adress under DHCP list? |
|
Answer» Here's something that I noticed today.. [1] Use MAC address filtering. [2]Turn off SSID broadcast [3]Don't advertise your router to the world. [4]Limit the number of IP addresses available to the actual number needed by your network 1. This can be done for the two machines not regulated by me, since those are, as you can see, detected in the list (Blackened out by me, though) how do I find out my own MAC adress? 2. What is SSID broadcast be and how do I find out where to disable that? - SSID SEEMS to be related to wireless networks. (Our network is not wireless) 3. Advertise in what way? I am blocking WAN Ping 4. Done. Limited the pool to use 3 adresses and making the lease time forever. Does that suffice for point 4?You can find your MAC address by using the ipconfig utility. SSID is for wireless. I assumed wireless capability. If the router has wireless capability, even if you are not using it, it still broadcasts SSID unless the wireless is disabled completely or SSID is disabled.The router has no wireless capabilities. Once I obtained the MAC adress for the other PC on the network I can disable all other MAC adresses that try to connect. What reason could there be that the Router does not show all the computers connected to more than 99% of the time? I disabeled the MAC adress for the IP that is 'connected' but it is still there.. Why is it there?Is that not your ISP IP address?The IP is not immediately released. You can release it from the particular machine, or reboot the router. The ISP's IP address should show up in the routing table but not in the DHCP clients table.After trying to decrease the IP pool Internet would no longer work on all PC's, I have tried assigning each PC an IP adress rather than having the PC's OBTAIN an IP Adress manually, but this would not work either. Since I haven't got the room to experiment all I want with this, I have kept the standard I reset the router BACK to the factory settings after complications arose (A bug they never bothered fixing, but I always manage to run into). This removed the IP adress that wasn't supposed to be where it was. Guess the problem could be considered 'solved'.... Be it in a way I had non quite expected. Or wanted. And, no I doubt it is the IP adress of my ISP. My ISP is not located in America..Quote ...some kind of Computer Science Corporation in my DHCP list does! CSC has been in the computer business for almost 50 years , http://www.csc.com/aboutus/history.shtml IP's assigned in ORDER, so, low number = 1st ones involved with ARPAnet (now DARPA), precursor to WorldWideWeb. Why it's on your client list makes no sense, just delete it. |
