Above is the the address of the BISQ exchange.
Now assume somebody say 18.104.22.168/24 is available in Russia or Brazil or India, then internet believes it, until Amazon complains to those ISPs who believed that information.
You may search internet on ‘IP Prefix hijacking’ for details.
Internet works on a protocol called BGP. Most specific information ( routing prefix) get prioritized.
Even Amazon is keep on advertising to the internet saying 22.214.171.124/18 is Amazon, if a small network operator with an AS may advertise 126.96.36.199/24 as them self.
So all the traffic from the internet to bisq.network goes to them and not to Amazon. It is called IP Prefix highjacking.
Of course after a couple of hours we can stop that but some times it takes longer.
This is why it is important to have your own addresses and AS number when critical services are running.
I hope to provide you more information.
Please keep in touch.
