Error Message Same Ip Address

December 7, 2009 8:18 am | Error Message

Two home computers showing same IP address?

So we have two computers in the house connected by a dynex hub on DSL provided by at&t. Sometimes the internet will be connected on both computers with no problems. However half of the time we get an error message on one or both computer screens saying that Windows has detected that both computers are showing as having the same IP address. When that happens we have to reboot the modem to reboot the internet for at least one or both of the computers. Does anyone know how to resolve that?

Get a router.
=
A router allows TWO or MORE PCs to be on-line at the same time.

An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. An IP address serves two principal functions in networking: host or network interface identification and location addressing. The role of the IP address has also been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." The original designers of TCP/IP defined an IP address as a 32-bit number and this system, known as Internet Protocol Version 4 or IPv4, is still in use today. However, due to the enormous growth of the Internet and the resulting depletion of available addresses, a new addressing system (IPv6), using 128 bits for the address, was developed in 1995 and last standardized by RFC 2460 in 1998

Excerpt: An IPv6 address is 128 bit value, with a logical structure, which can be assigned on a network interface, making the host reachable over IPv6 on that interface on that address. An IPv6 address can be assigned on an interface that has an IPv4 address assigned also. IPv6 addresses are part of the IPv6 header where they indicate origin and destination of the IPv6 datagram. An illustration of an IP address (version 6), in hexadecimal and binary.Source IPv6 addresses are always unicast addresses, uniquely identifying the originating interface. Destination IPv6 addresses are unicast, anycast, or multicast addresses. Addresses are 128 bits long and have several distinct structural definitions, except for the loopback address and the "unspecified" address, which have no specific structure. Unicast (and anycast) addresses are typically composed of two logical parts: a 64-bit (sub-)network prefix used for routing, and a 64-bit host part used to identify a host within the network. A network prefix consists of an ISP-assigned value in the most significant 48 bits of the address. This value can be self-assigned in case of a unique local address. The 16 bits of the subnet field are available to the network administrator to define subnets within the given network. The 64-bits interface identifier is either automatically generated from the interface’s MAC address (using modified EUI-64 format), obtained from a DHCPv6 server, or assigned manually. A link-local address is also based on a interface identifier, but uses a different structure for the network prefix. The prefix field contains the binary value 1111111010. The 54 zeroes that follow make the total network prefix the same for all link-local addr…More: http: //booksllc.net/?id=2450467
