Briefly;

// to list blocked IPs;
iptables -L INPUT -v -n

// to delete (remove block) the blocked IP;
iptables -D INPUT -s x.x.x.x -j DROP

// To add (make reliable) the IP addresses to the whitelist;
// INPUT: to inputs, OUTPUT: to outputs
iptables -A INPUT -s  x.x.x.x -j ACCEPT
iptables -A OUTPUT -s x.x.x.x -j ACCEPT
