So, what happens with 104.149.1.112? Does anybody get to actually use it? Or is it just a placeholder? I never really paid a lot of attention to CIDR until I started to need a lot of IP addresses for websites, email, etc. for TLS/SSL certs. I stumbled upon this server where I have my other two and I couldn't pass up $31 a month. I can't reasonably backup properly at home, too slow a connection. Chris
