can only UNIX servers use IP banning? why?


For a certain troll-ridden forum I visit, I wondered why the site doesn't use IP banning like LQ--evident because the banned regularly make new accounts. I reviewed what IPs are and what IP banning is, and learned:
Quote:
Unix-like operating systems commonly implement IP address blocking using TCP Wrapper, configured by host access control files[1] /etc/hosts.deny and /etc/hosts.allow.
Does that mean, as implied, that only UNIX servers can IP ban (or at least IP ban easily)? Why would that be? Is it just some design feature that, after decades, other OSes haven't figured out how to implement? I guess it would explain why so many forums don't use it.

1. "Unix-like" != "UNIX"

2. An explanation of how X implements feature Y does not mean only X can do Y.

Banning, although that name is rarely used, is also a feature of modern firewall software. It is available on anything that uses a modern firewall.

That is not implied at all, as boughtonp pointed out.

Forums can or can not ban IPs regardless of the operating system they run on.

But there's a difference between banning a user, and also banning their IP.
Sometimes IPs are used by more than 1 person, so it would be unfair to ban the IP just because one user is trolling.

Do you have any definite info on this? My guess is not, and afaics a much more likely explanation is that these people use varying IPs through TOR or sopme VPN.

The forum would implement the ban in PHP or whatever server-side language it's written in. It wouldn't use anything specific to Unix or any other OS.

IP bans can be by subnet, so they can ban his ISPs/proxies/VPNs if they want to.
