From the network security and availability point of view, it is preferred that digital exchange uses their own IP addresses. Our researches shows that 90% of the digital exchanges are hosted in Cloudflare, AWS or Incapsula. Also none of the digital exchanges uses their own IP addresses.
Couple of issues are identified.
Too much centralized, traditional banks online transactions are more decentralized
Your addresses are summarized with other services when the cloud service provider advertise the IP segments to internet, which means a bad actor can advertise a detailed prefix so that you are not reachable from the internet until the upstream ISPs identify and stop the bad actor ( IP highjacking).
Less redundancy as not multihomed.
We are concerned as network engineers, whether these issues are thought or not.
Would like to know what the network designers of BISQ think regarding our above concern.
