How do I use network package with 5 Static IP address

[Vis1/0N]

Spoke to someone finally today - they will get back to me. My public address is showing as 41.x.y.z and the router is showing WAN 10.x.y.z and they had allocated 105.x.y.z/29 as my public static ip. I am not skilled past basic networking, so there is a lot lacking on my part. Does it look like there is some other NAT/tunnelling happening along the way? Or that the allocation has not really been done properly yet?

I see that I can ping the gateway and it replies with the gateway IP (.101). I ping the allocated IP (.102) and it replies from the public IP. The Public/Network IP does not respond.

As a side note they allocate /29 - subnet mask 255.255.255.248 so that allocates 8 IPs, one of which is broadcast and another the network IP. So if it is 105.x.y.100, the gateway will be 105.x.y.101, 102-106 is allocated for use, and 105.x.y.107 will be the broadcast.

ISP's have started using private ranges for customers "WAN" and then NAT a whole bunch to a single public IP. I would hazard a guess that this is their basic setup and they havent configured things for your static IP range.

They would likely need to change your WAN router IP to one in the assigned range and their side to the other in the range. Depending on how they configure this, it could simply be done using attributes, and would require a reboot on your CPE rather than them configuring. Many ways to accomplish this

Dont really know what you mean in the bold part. Your IP ranges are also out, for a /29 in that kind of number, it should be x.x.x.96/29, first host is 97, last host is 102
I also dont think you can assume the gateway will be the first IP in a range, it comes down to their standard and what they assign. I am not sure what you mean when you say you ping the allocated IP and it replies from the public IP. Where are you pinging this from and what exactly is responding? They might have this range setup somewhere else and have an IP clash as well

There is no bold part from my post, 100-107 was an example. They did communicate that my static public IP address was 105.x.y.240 (a week after installation). Prior to that checking the router WAN port I gathered that I am 10.x.y.z. Checking WhatsMyIP I am in 41.x.y.z.

They responded with the range and gateway yesterday. They could have noted that it is setup as 105.x.y.240/29 from the start and saved me some time, and communicated a diagram.

when you say you ping the allocated IP and it replies from the public IP.

Remoting to my home machine and pinging:
Allocated Public IP (105.x.y.240) timed out.
Gateway 105.x.y.241 Reply from 105.x.y.241
IP Server 1..5 (105.x.y.242...246) reply from 41.x.y.z (Which is the public IP according to WhatsMyIP)

The good news that (as per earlier advice) I have connected a LAN cable and manually setup the 105.x.y.242 with the gateway 105.x.y.241 (these details provided yesterday) and this machine now has a public IP (and the reply in the ping is from 105.x.y.241, not 41.x.y.z). I guess the machine is now directly exposed to the internet. What I will try later is setting the next available static IP onto the old router. Also will post a diagram later for others to grasp their setup.
