What DNS server should be set up to activate real-time protection in Sophos Anti-Virus on a Plesk server?

Answer

Any DNS server, public or private, can be used. The option is given so as to not overwhelm private servers with DNS queries.

• Google:  8.8.8.8 & 8.8.4.4
• Control D: 76.76.2.0 & 76.76.10.0
• Quad9: 9.9.9.9 & 149.112.112.112
• OpenDNS: 208.67.222.222 & 208.67.220.220
