ok... so.. i know that IP add can change one..
\so if let's say i got this IP A, den some how or other, the
person manage to change the IP into B. is IP A still valid?
depends on how the IP has been changed(technically or just
reboot modem). A computer is allowed to have more than 1 IP at the
same time...a computer can also take in IP A from the ISP but
broadcast IP B out...so in short...to find out whoever U want to
find...U need the ISP's help together with the exact date and
precise time the IP that U have was found.
