are you using Network Address Translation at the Gateway? Is your external IP the address of the last hop router/device Try looking at Shields Up on www.grc.com this will help you check for security weaknesses and give you your IP, if this corresponds to your machine IP then its publicly accessible. Servers have static IP's. workstations have DHCP addresses. a private range 192.168... may make it easier to guess important machines on your network. i've been told to avoid this. -----Original Message----- From: Farrugia, Paul [mailto:pfarrugia@xxxxxxxxxxxx] Sent: 29 October 2003 16:15 To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] IP Addresses Hi, Sorry if this is a little confusing, this is the first time I am dealing with something like this and I am trying to word this as best I as I can... All of the computers (workstations and servers) on my network are on a public ip address range. They are currently using the scope of 208.196.79.1-208.196.79.250. It has been like this since before I was here. Does anyone see a problem with this??? From various threads I have read I see that most networks are configured on a private ip range ...192.168.1. xxx...anyway...I wanted to know if this something that I should be looking to change? Is this just common practice or is there a reason for it? I know that changing the ip's on my servers will be more a pain then I need right now but as far as the workstations go..would I just have to create a new scope and have the DHCP server give out those addresses? Thanks in advance for any help Paul. **************************************************************************************** This email and any files transmitted with it may contain information which is privileged and confidential, the disclosure of which is prohibited by law and intended solely for the use of the individual or entity to whom they are addressed.
