New internet line. 1 wire, 5 IPs

Hello, we are in the process of upgrading our internet line and our new ISP said that we'll be getting one wire from them and that we're entitled to 5 public IPs.

My question is, can I put this cable on a (L3?) switch and configure specific ports on the switch to pick only one of the available IPs? What I'm looking for is to split this one cable the ISP is giving me, to 5 individual ones, but each of them to be able to only obtain the IP I want.

Example

Cable from ISP coming in to the building( 192.217.22.1/29 ) | | L3 switch? Port 1 | | --Port13 -- Router ( 192.217.22.2 ) --Port14 -- Router ( 192.217.22.3 ) --Port15 -- Router ( 192.217.22.4 ) --Port16 -- Router ( 192.217.22.5 ) --Port17 -- Router ( 192.217.22.6 )

What I effectively need to do, is to be able to give a cable from let's say port 15 of my switch, to someone with a router of their own and tell them that they can use 192.217.22.4 as their public IP without them being able to get any of the other IPs.

I would also like to be able to allocate bandwidth ratio for each port/IP.

Is this something an L3 switch can do? I might even be approaching this thing wrong.

Thanks in advance.
