What IP address ranges does PlusNet use?

[#1]

I'm using PlusNet Value broadband and I've been asked what IP address ranges I'm likely to be using, so that my account can be allowed on a particular server which limits who can access it and from where.
I have looked up my current address and www.ripe.net tells me this is part of the block 87.112.0.0 - 87.115.255.255. That's a good start. Are there other address ranges I might be using, perhaps tomorrow if I'm disconnected and connected again?
Yes, I know I could upgrade to a more expensive service and ask for a static IP address. But I hope not to need to do that.

I would say it's not much of a limit when they do it by block.

@Bob - thank you very much. I did try to search this forum for a post similar to that one, honest, but I didn't try very hard.
@itsme - I didn't set this server's policies. The server can, though, now define "mhi + password accepted only from PlusNet broadband" rather than "mhi + password accepted from anywhere" (or, as it is so far, "mhi not accepted at all"). That cramps the style slightly for a scammer wanting to use the same server.
