The ISP just doesn't corporate and we can't change it since the state pays
the contract and it has been renewed for 2 years some months ago.
Hamachi doesn't work for us, I've tried it.
And isn't charging a fee for a service the same as selling a good? Both
involve a thing and money traded.

If you need blocks of global IP addresses, ask your upstream ISP for
the blocks to be assigned to the networks first. ISPs receive blocks
of IP addresses for the sole purpose of delegating to customer
networks. Provided the customer network has a documented justifiable
need for the amount of IPs.
ARIN does not sell IP addresses. IP addresses are not for sale,
although, there are fees involved in obtaining IPs from ARIN, the
main criteria, is you first must have a justifiable need for the
minimum sized block, that is
You only go to ARIN if you need an allocation of least a /20 (4096
ips), or are multi-homed with 2 or more ISPs and need at least a /22
(1024 ips), and can get the documentation to show that you will meet
the utilization criteria.
This is all described in the Number Resources Policy Manual:
If your ISP won't assign needed IPs to you, it might be time to switch
ISPs or get a renegotiation of the contract with your ISP, including
provisioning of IP addresses that you have documented need for.
If the ISP is not willing to work with you to get the IPs you need...
then what good is it to get IPs delegated from ARIN or from someone
Only for your ISP to then tell you they aren't willing to announce the
IP addresses for you, or to grant you a BGP feed for announcing
Unless an ISP of yours does extra work to provide the connectivity,
you'll have no means to actually use those newly acquired IPs: it's
not possible to simply assign one to your router and be done with it.
Your ISP has to designate a static IP that your router can use.
Your newly acquired IP block needs to get announced by some ISP
connect to your sites, who is willing to forward traffic addressed
to those IPs to your sites.

For such an application I would suggest utilizing PRIVATE IPs and a
VPN application, for example you could subscribe to a service such as
Hamachi (for example) to create connections between locations.
Only allow users to "share" resources when connected to the VPN service.
Or get your ISPs to provide each location at least 1 static IP for a
in that case, with a large number of schools, there is a good chance
some would be already utilizing PRIVATE IPs, and some could be
utilizing overlapping ranges.
One might look into applying for IP addresses for that
non-connected network, then, to avoid conflicts with 10/8
172.16/12 and 192.168/16 addresses already in use.
