I understand where you are comming from, but in this particular case, I personally believe you are just splitting hairs....
I have a 50MBps fibre feed from VM and I have a DSL connection from Eclipse Internet facilitating a BT line.
The DSL connection trickles somewhere around 1.4 - 2.1 MBps, which is not really Eclipses or BTs fault, but never the less, I am paying for "up to" 20MBps, where as on VM I am paying for 50MBps.
That I don't always get 50MBps lies in the nature of the biest, as the chain is only as strong as the weekest link.
But I ca nsay, that whenever I donwload something from within the VM network, I certainly do get my aprox. 6 MByte/s
And if VM would provide something like a /28, or at least a /29 subnet (free of charge idealy), I would probably kill my DSL completely. But I still ahve to say, that service wise Eclipse is one of my favourite ISPs
