I don't think it's fair to say that they don't have control of DNS or
public IP space. I've got a customer now leasing bandwidth in a very
similar setup...a 10Mb fiber connection to a local switch. These guys are
assigned then assigned a /26 to use as they see fit. Their DNS is
maintained locally on the "public" side of the network. They also have a
router that NATs from the private internal network to the public block of IPs.
In your case, you have a /24 block available on which you host all of your
network. Assuming that your provider has the Ethernet MAN type service
available, and you want them to use your current block and setup this
service, you'd have to allocate one of your local addresses to them to use
on their router's Ethernet interface, and then change your nodes to point
to the new gateway. You'd still have full control of DNS and your /24 IP
allocation, though you'll have to work closely with the provider on policy
decisions.
If your provider doesn't offer this service and you go with a new provider,
you'll either have to readdress your network or implement NAT with
non-RFC1918 addresses on your inside network (not recommended). In either
case, it's still possible for you to maintain control of your address
allocations.
