Some groups, like MIT, were given literally millions of addresses, more than they can ever use, but it’s not really practical for them to give them back now. Ask anyone who has to deal with CIDR; earplugs to muffle the blood-curdling screams of terror are optional.) Over the next few years, IPv6 will be phased in, increasing the number of addresses to 2 (3.40e38, give or take), enough for everyone and all their major appliances to have an address. There’s only so many numbers out there, at least as far as the computer is concerned.(Basically, each of the four parts in the “dotted quad” address can only be between 0 and 255.)

(These ‘leases’ usually only last for a few days, and sometimes only a few hours.) At the end of the lease, you may be able to negotiate a new lease, but you can’t be sure of it. Your ISP, cable company, or whoever, might let you have a dedicated IP, but they’ll probably charge you extra for it.
It’s more likely, though, that they can’t or won’t help you…
