Hello,

In hosts section of hot spot the table has " Address" and "To Address" columns , which have identical IP. Can anybody advise what do these columns notify. I wish to block some IP in this host list

you block those ip. but if you have dhcp server enable they will have a new iup on their next ip-pool.

the best to blocked them is to use their mac address to identify specific connected client.
here's how to implement.

add rules in firewall/filter then using their src mac address tag it as forward and drop/reject
