Wow...how old is that link? BT Infinity with a maximum of 22MB? 🤣
According to Google it was first indexed 6 years ago but no telling how long it has been up as it isn't dated.
I was thinking that any information contained in that article couldn't still be current so I searched for more up-to-date info but drew a blank leaving me no alternative but to ring BT Business.
This was almost futility in itself but I managed to extract the following info that does not differ too much from the article you linked to;
Halo comes with one free static IP address (although I don't see it mentioned anywhere in the emails/documentation I received nor in my account details online)
Extra static IP address in addition to the above are charged as follows;
£5.80 per month for 1
£11.50 per month for 5
I am assuming prices quoted to me over the phone are plus VAT as this is a business facility after all.
Hope that helps!
The OP was asking about static IP Addresses in regard to FTTP not FTTC which you seem to be referring to with your reference of a 22MB/3MB service.
When I originally signed up for FTTC it was called Infinity but AFAIK that name was dropped in 2018 and it was rebranded as Superfast.
FTTP or Ultrafast as it is now known offers three options100/500/900MB and I’ve been waiting patiently for BT to install my 900MB service which will cost less than my 80MB/20MB service!
