I have a few questions about hosts.allow

1) There are 2 IPs in this file. I did not put them there. This is a dedicated machine. The IPs go to a Canadian hosting company. I am not in Canada and those are not my IPs.

2) Does my provider have the right to add IPs to this file without my consent?

3) I have already commented them out, of course, but I am concerned.

What would you do if it happened on your server?
