[QUOTE="EvenStranger, post: 1287119, member: 181804"] Last paragraph has the questions if you want to skip ahead. There are number of concepts here that need to be addressed. First, IP addresses are kind of like phone numbers - moving from broader information to more specific information. Your phone number would start with a country code, in the US that's 1+, then area code, denoting a large region within a state usually, then local code specifying your neighborhood or community, and then exchange, or your phone. Same with IPs. IP addresses are divided into four sets of numbers, or octets (based on 8 binary digits from 00000000 to 11111111, or 0 to 255). Your first octet is the broadest scope. It can literally cover millions of websites and individual internet accounts. Then it proceeds to narrow down through the second and third octets to finally end at the fourth octet, your network's IP. If every possible numeric combination was assigned to a computer, our current IP setup could handle about 4.2 billion (255^4) connections. However, large blocks are set aside for government use, education, different countries, or just overhead. Several large blocks are set aside also for private use. IPs beginning with 10.x.x.x, 172.16.x.x and 192.168.x.x are used by routers to map an internal network without requiring multiple public IP addresses. Think of a switchboard at any company - they have one public phone number, but once the call reaches the switchboard, it can be passed to an extension within the company. Your router is doing the same thing. Now, as to why you are receiving two different public IP addresses on two different connections to supposedly the same network, I don't know... If it's the same network, both devices should be showing the same public IP addresses, just like two phones in the same company would be accessible through the same main number. I'm wondering if you are certain you're connecting to the correct wireless network. Netgears are pretty prolific, and if you're using the generic Netgear name as your wireless network, it's easy to get it mixed up with someone else's network. Is there a VPN connection going on somewhere? Proxy software that routes your computer through a remote host? Do other computers behave the same way - a 69.0.0.0 wired and a 173.0.0.0 over wireless? If not, then you know it's a setting on your computer somewhere. I hope this helps... let us know what you find out. [/QUOTE]
