Is there a command or some way to tell from the Internet if a company has a static IP address?

Not sure what you mean.

Are you talking about a specific website, or the IP addresses a company uses internally ?

Most web servers probably use static IPs, especially bigger companies.

Dynamic IP's are probably only used for very small businesses running from home.

I hope this helps !

I meant any company with broadband DSL service; some are dynamic and some ar static. How can you tell which it is from the outside?

You really can't easily, except by monitoring the ip over the long term.

Some will list it in the reverse dns lookup, but some don't.
you can use sites like http://www.dnsstuff.com/ to do a Reverse Lookup on the ip address.
Some will show a name something like dsl-static-w-metro-isp-pool-1234.isp.net
Some ISP's don't provide that reverse dns at all on dynamic lines, and some have other info in the reverse dns, but don't say static.
So there is no easy RELIABLE way to tell from the outside.
Although, if it is for a specific website, you could check http://netcraft.com/ and see if they have indexed it.
