HOST NAME

How to block?

Answer 1

I don't know by name, but in the case of freebsd, you can use this host's IP
host -ta torproxy03.31173.se | awk '{print $4}' | xargs -n 1 ipfw add reject tcp from any to
blocks addresses. this is in case the host address changes
, but in general, you need to look at fail2ban

Answer 2

No way, nginx does not resolve the return, otherwise it would slow down (and even if I learned it, I don’t advise turning on the resolve for the sake of one host).
iptables -A INPUT -s torproxy03.31173.se -j DROP
