What happens if two computers have the same IP address? Will one computer be unable to download thing or connect to the Internet? Will one computer be able to see and control the other?
Two computers can safely have the same IP address in certain cases. In most cases, if those two computers are on the same local network, it breaks connectivity for one or both of them.Internet protocols work by sending small, individually addressed messages. Each message can be routed differently. Connecting to a website usually involves at least tens of these messages, and often thousands. If you only get half of the messages, while the other computer with your IP address gets the other half, nothing will work.In almost all cases I know of, well-designed protocols simply won’t work. Duplicate IP addresses don’t make one machine controllable by the other, they just break network connectivity.Here’s more information.Networked computers today usually have at least two addresses:A MAC address that they use to talk to other computers on the same network, for example in your home, or on one part of a floor at an enterprise. This type of address can’t cross IP routers.An IP address. This is used for routing messages to and from other networks, and can be used on top of MAC addresses to route messages within a network. Almost everything we think of as networking uses the IP address.Many machines in the world have the same IP address. For example, most home routers come pre-configured to hand out network addresses like 192.168.0.*, or 10.0.0.*. These are private IP addresses. They are only routable within that private network, and on that single network no other machine can have the same private IP address. Proxy servers or network address translators (NATs) can help such a computer interact with the rest of the internet by changing the messages to look like they’re coming from the public IP address of the proxy server / NAT. When it receives messages on their public address, they know which private machine to forward it to.Public IP addresses are intended to be globally unique. Internet protocols know what routers to pass through to reach the network that IP address belongs to, and the address resolution protocol (ARP) helps determine which machine on that network owns the IP address and receives the messages.If two machines have the same IP address on the same physical network, it’s a problem. Network hardware gets confused about which of those machines really own the IP address. It can refuse to deliver messages at all, or it may randomly choose which of the computers gets each message. This will break most all protocols.
What are TCP, UDP, Proxy, port, local host, ip address?
TCP and UDP are simply put two ways of sending data from one place to another. TCP ensures that the data you get is always right, so it does a lot of checks for you. That makes TCP connections a bit slow. UDP tried to make the data reach you as fast as possible. It sometimes makes small mistakes because of being in such a hurry I would suggest that if you are downloading text documents like ebooks etc. use TCP If you are listening to songs, use UDP (you will not even notice the difference of sloppy delivery) Proxy (Server) is a large computer that does the surfing for you. So assume that you want to go to yahoo.com, yahoo will find it very hard to handle all the people who want to see yahoo.com at the same time. A proxy server can then visit it for say 100 people and next time, if you ask for yahoo.com, it can send you the page all by itself (so yahoo is not overloaded) and you think the service is faster. IP address is a way all the computers connected in the internet identify themselves. Each computer is given 1 unique IP address (much like we all have postal addresses). So if you know the IP address of each computer, its easier to reach that computer, rather than meander arounding asking people whether they know where this computer is connected. An IP address looks like 192.168.12.234 Port is like an electric socket at your home. Assume that you hv two TVs at your place, and both are tuned to different channels. So even if the channels knew that they are broadcasting the stuff to the same house (or IP address), they know that eventually it goes to two different sockets (or ports). Your computer has one IP address, but multiple ports. These port are numbers like 80, 3012 etc I am simplifying all these terms for you to understand. I will recommend that you talk to your ISP or a local "computer-expert" to help you identify the exact proxy, IP address, port etc for you. All the best!
How can I hide my IP address on LiveJournal?
I am in this community where I don't want my IP address revealed on LiveJournal.com. The person turned on the option which logs a person's IP address when they comment a post. I want to still be in the community, so I need to find a way to hide my IP address when commenting. Is there any software I can get for free that allows me to do this? Or any cheap software that allows me to do this? That will let me hide my IP or make a fake one up? Thanks.
Is there any way i can stop someone from getting my IP address?
I get freaked out about people when they say they can track you down by using your IP address...Is there anyway to stop it? I mean even stop them from seeing the City and State you're from. Please and thanks * Please give me a website where i download something to keep everything anonymous including where i'm from and etc..
Any program to change IP address in every 30 minutes?
What you are looking for is called a VPN, a Virtual Private Network. Check out these two sites. You can used Proxpn for a week for free, but it has a band width restriction of 1,000 to make you want to buy it. Both websites give you a description of what a VPN is, but basically you log into a server which gives you an encrypted IP address from their servers, from the Netherlands, UK, or in the U.S. http://proxpn.com/ http://www.purevpn.com/
