Point domain at my Plusnet space

[#1]

Hi
I have a PlusNet Broadband Plus up to 8mb account (which I should probably upgrade as that's an old package).
I have a domain registered with Low Cost Names, and hosted elsewhere.
Is it possible to host it using my PlusNet space (how do I tell how much I've got?) instead, by keeping it with LCN but pointing it to PlusNet's nameservers?
If so how would I go about this at the PlusNet end of things - and how many domains could I host in this way?
Many thanks for any pointers, and sorry if this has been asked a thousand times: I did try to search.
Cheers

While the community search is a bit iffy, this was the first page found on the PN home page search for "nameserver":

Thanks. I must try harder.

You can host one free domain with the Broadband Plus account

and you get 100MB of webspace with 100MB of daily bandwidth allowance
