@aravinth_chakravarthyr_173918 you just need 1 host IP at a minimum. It is the contact list used for making the initial connection to the cluster so best practice is to include at least 2 IP addresses for at least 1 DC just like you would for the seeds list in case the first node is unresponsive for whatever reason.

It is a comma-separated list and the format is -h "IP1, IP2, IP3". Cheers!

Google doesn't pay attention whether you ping them or their DNS server. I cannot find the commentary right now, but when arguing how they handle online essay help DNS attacks and DDOS outbreaks a Google engineer described the level of regular legitimate ping traffic.
