📄️ DNS & rDNS overview
The DNS & rDNS page of the YorkHost client area: where to find it, overview of your domains and IP addresses, meaning of each state (Managed by YorkHost, Zone ready — point the NS, External DNS, Not delegated, sub-yorkhost.fr subdomain, read-only cPanel hosting) and what to do in each case.
📄️ Point a domain to YorkHost
Have YorkHost manage the DNS of a domain: prepare the zone, replace the name servers with ns1.yorkdns.com and ns2.yorkdns.com, propagation delay, .fr domains (AFNIC checks that the zone already answers) and checking with dig.
📄️ DNS zone editor
Manage the DNS zone of a domain at YorkHost: record types and examples (A, AAAA, CNAME, MX, TXT, SPF, DKIM, DMARC, SRV, CAA, TLSA…), protected NS and SOA, TTL, e-mail templates (Google Workspace, Microsoft 365, Zoho, Proton, OVHcloud), BIND import / export, DNSSEC and read-only cPanel zones.
📄️ Reverse DNS (PTR)
Change the reverse DNS (PTR record) of the IPv4 and IPv6 addresses of your YorkHost VPS and dedicated servers: where to find it, fully qualified host name (FQDN) required, forward-confirmed reverse DNS for a mail server, states, reset to the default value and checking with dig -x.
📄️ Bulk rDNS
Change the reverse DNS (PTR) of many IP addresses at once at YorkHost: CSV or JSON export, edit and upload again, accepted formats with examples, "Check only" ticked by default, limits (256 KB, 512 addresses, hourly limit: whole batch refused).
📄️ API and MCP
Manage the DNS of your domains and the reverse DNS of your YorkHost IP addresses through the client API (/client/v1/dns, /client/v1/rdns) or an AI assistant (MCP): dns:read, dns:write, rdns:read, rdns:write permissions, curl examples, MCP tools, limits, errors and precautions (protected NS/SOA, read-only cPanel zones, PATCH replaces the record, /dns ignores the service restriction).
📄️ FAQ and troubleshooting
Solutions to common DNS & rDNS problems at YorkHost: domain stuck on "Zone ready — point the NS", name servers refused by the registry (.fr, AFNIC), PTR that does not change (cache, TTL, dig -x), read-only zone (cPanel), validation errors and change limit.
