OK, You've been allocated a /29, this is 8 public IPs. As you note
above, the first IP is the network address (.88), and the last is the
broadcast address (.95). Other than this, the ISP expects your router to
be on the second IP (.89). This is typical, and is similar to what my
ISP gives me.
So, what I would suggest you do is configure your machine as follows:
> iface eth0 inet static
> address 41.134.19.{90-94} # Pick one of your five free IPs

> network 41.134.19.88
> broadcast 41.134.19.95
> gateway 41.134.19.89
Next, and this is quite important, configure your router into Multi-IP
mode. Most broadband routers expect you to have one IP and so will NAT
anything that comes in. You will need to tell your router to pass
through all traffic for your /29 block. How you do this depends on your
router.
