Thanks for all the responses! Seems like I was right about doubting this. Regards -- Filip Hruska Linux System Administrator Dne 1/4/18 v 20:20 Matt Harris napsal(a):
They're probably using GRE or other sorts of tunnels, I'd imagine? It would likely involve increased latency, as any packets coming to those addresses would hit them first, and then be tunneled - either over the public internet using gre or some kind of vpn, or perhaps via a private connection or even an IX, to you? As far as outgoing traffic from those addresses, you'd probably need to make sure that any upstreams you're sending packets to from those addresses are not running urpf which would cause them to be discarded, or otherwise get around such a configuration.Take care, MattOn Thu, Jan 4, 2018 at 1:13 PM, Filip Hruska <fhr () fhrnet eu <mailto:fhr () fhrnet eu>> wrote:Hi, I have stumbled upon this site [1] which seems to offer /27 IPv4 leasing. They also claim "All of our IPv4 address space can be used on any network in any location." I thought that the smallest prefix size one could get routed globally is /24? So how does this work?
