Hurricane Electric Free DNS is a hosted portal for managing DNS zones. It supports record types including A, AAAA, ALIAS, CNAME, CAA, MX, TXT and SRV, forward and reverse zones, secondary (slave) zones and dynamic DNS through HTTP updates or ddclient-compatible clients. According to the provider, the service runs on geographically diverse servers with IPv4 and IPv6 support. It is delivered as a web portal with nothing to install, and the site labels it as an open beta.
Hurricane Electric is a privately held company headquartered in Fremont, California, and operates its own global IP network and its own data centers in Fremont. The service therefore falls under US jurisdiction, and the DNS data for your domains is managed by a US provider. The service page names no privacy policy, no GDPR statement and no data storage location. European organisations that prefer not to rely on a US provider for DNS can combine the secondary-zone feature with a European primary or secondary nameserver.
