Managed DNS Services
Managed DNS Services Overview
What are Managed DNS Services?A DNS server manages resolution between public IP addresses and their host names. A managed DNS service relieves much of the hassle associated with hosting your own DNS server. When self-hosting a DNS server, downtime can disrupt service delivery and requires troubleshooting. Managed DNS services provide far more resilient networks of servers. By steering traffic dynamically they improve access to digital assets and reduce DNS load time.
Managed DNS providers may also offer security features such as web application firewalls (WAFs), DDoS protection, web filtering and anti-malware. Many managed DNS providers specialize in failover, a common feature to ensure uptime by redirecting traffic away from endpoints that have gone down. Alternately, secondary DNS is a strategy to prevent outage whereby multiple authoritative servers are always available to answer queries.
