No it doesn't.
I remember the first time i setup a rack of servers in a cage in a datacenter for a company i founded. We bought a block of IPs in bulk and then we bought an interconnect from a provider within the datacenter. To get those IPs pointing to our server we had our severs announce ownership over BGP. It's that easy.
Usually BGP messages are filtered out by routers. Otherwise home users would announce ownership of the Google addresses and have all those messages come to them for example. But if you have access to an interconnect in a datacenter you can state you own whatever IP addresses you want. There's really nothing at all stopping it right now.
- icedchai 7y agoMany upstream transit providers have route filters in place. They won't accept any route, like they did in the 90's. Some still do, of course. Also, normally you have your router announce routes over BGP, not your servers.
