Well, they haven't quite run out. THere's still millions of unused addresses available. The allocation of new sets of addresses past a certain level of the hierarchy, has run out. I.E. (and this is really primitive understanding on my part): the www part of the www.xxx.yyy.zzz address space has been filled in. There's still plenty of addresses left (for a little while) in the yyy.zzz parts of each of them. The xxx etc stand for numbers between 0 and 255, so in theory there are 256 x 256 x256 x256 (or about 4 billion) IP addresses total, but reserved numbers in each of those positions means there are somewhat less than that which can be used by the general public. The next generation of IP addresses, IPv6, have the form ssss.tttt.uuuu.vvvv.wwww.xxxx.yyyy.zzzz where each block can range from 0 to 65,535 or there are theoretically 65,536 x 64,536 x... (or 340,282,366,920,938,463,463,374,607,431,768,211,456) possible addresses available. The way those addresses are divvied is very complicated, but the bottom line is that they don't expect IPv6 addresses to run out until we have a multi-galaxy civilization to provide addresses to.
