Yeah it changes less if your on Cable or DSL, but anyway there's absolutely no way to hide an IP address -- the computer your talking to would have no idea where to send the packets to if it didn't have an address. If you go through an anon. proxy ... that would be your only way ... and that would not hide the IP it would just tell the target computer to send the info to the proxy which would then route it to you ... its slower and less secure, not to mention allot of Anon proxy's are banned by webmasters because people think they can do anything they want through them and not get caught (not true by the way, if you get the FBI or any agency after you for something you do on-line -- they can trace you right through the proxy's so don't think your invincible if you use one.)
Well, imagine trying to communicate with someone and you expect an answer, but they don't know who to reply to.
The ONLY reason someone would really want to hide their IP is if they're a Cracker - evil hacker - and they want to "spoof" their address to crack another system.
And this is possible ... but if you want to know how to do it, you'll just have to figure it out ...
As far as changing IP's with dial up/cable/dsl - you're getting an address from a Dynamic Host Configuration Protocol server. When you release it, your system is telling the server you don't need the address anymore and it can free up the resource (because it has a limited number of them). If you renew, immediately, the server has the ability to remember your MAC address and will likely give you the same address if it hasn't been leased to someone else.
If you have an always on connection - such as cable or dsl - your side will begin contacting the server to renew the address when it is half way through the lease period. If it can contact the server, it will renew and then wait for half the renewed period. If not, it will keep trying periodically.
Unless your dealing with someone thats really good, there's no way to trace you using your IP address anyway. The most someone would be able to get would be the last hop the information took before it reached your system. A whois or trace would not give away your information such as exact name or address or anything. So the common person would not be able to find out much except the general area your in and what ISP you are using.
I have to disagree with you Tech. If you're running a website, it's pretty easy to get someone's address.
And if you have NT or Linux it's pretty easy too, if, as they say, they're running a discussion board and the other person is sending traffic directly to them. One could simply run NetMon on NT and see the traffic. If someone is running a website, it's pretty common knowledge on the net how to do the scripting to report the IP address.
It's not the IP address that changes on each hop - it's the MAC address of the source that will be changed.
But, this is the way the IP Protocol was designed. It HAS to have a source and destination IP address in order for communication to occur. It's a TWO WAY conversation. The only way to "hide" an IP is to substitute it with a Proxy or with Network Address Translation. Either way, the conversation still has to, technically, be traceable.
Serious question guys...I have a friend on another message board...He posts behind an alias...The other guys on that board claim that they as users...Not moderators...Can see his IP address and out him...Is there any truth to this claim?
