We have (had) a raq3 machine hosted by clever.net, bought out by Interliant and now by Interland. It had 2 ip addressess on it, and then we got a third in a completely different range.

Last weekend we lost 2 of the addresses but the third stayed up. Interliant and Interland both claim that the machine is on the other's permises - who knows where it really is?

The two addresses that are no longer visible on the internet are almost visible via tracert. The final step before ours is 64.244.0.103 I suspect that this is a router at either Interland or Interliant (who could know?) that needs to have our IP addresses registered on it.

Anyone have any ideas about that?

What are the two addresses that are unreachable? A traceroute should show where they die, and hopefully point you in the right direction as to which data center they are in.
