Reliable ISP?

Thu Nov 18 14:32:46 MST 2021

I have a VPS with a number of websites that share the same IP and I have 
Lets Encrypt SSL on each.  You can do SSL with shared IP.  I do recall 
back it the day having a static IP was a requirement for a cert... So 
maybe that depends on who is the cert authority.

I had a conversation with a Cox support person about how to configure 
multiple IPs and he was as confused as I am.
