What CIRA Anycast DNS is
CIRA Anycast DNS is secondary DNS infrastructure for organizations. It routes queries to the closest nameserver and uses international nodes to absorb offshore DDoS attacks. CIRA says its global DNS servers peer with more than 5,000 networks and advertises a 100% uptime service level agreement for DNS resolution. The service supports DNSSEC, signed zone transfers with TSIG, and IPv6 DNS resolution. Teams can provision, monitor, and manage DNS through a web console, REST API integration, and a notify listener that automates new DNS records. Reporting provides hourly, daily, and monthly zone reports, with alerts for zone-transfer problems. CIRA says networking and DNS experts monitor the service 24 hours a day and that 24/7 technical support is available. Listed capabilities also include custom blocklists, safe-search controls, and advanced activity reports. CIRA was founded in 1998, is headquartered in Ottawa, Ontario, Canada, and states that it is ISO 27001 certified. The order form sets limits for zones, records, and monthly queries, with extra charges potentially applying when limits are exceeded.
