Abstract: A server hosting system provides managed servers for tenants of the server hosting system. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names (FQDNs). Furthermore, the server hosting system provides routers for the tenants. The router for a tenant can receive a Domain Name System (DNS) update message. The DNS update message is a request for a DNS server to associate a tenant-side FQDN with a tenant-side IP address. This tenant-side IP address can concurrently be an IP address of a managed server of another tenant. In response to receiving the DNS update request, the router sends a DNS data message to a management system for the server hosting system. The DNS data message indicates the IP address, the tenant-side FQDN, and an IP address only associated with the given tenant.

Abstract: A server hosting system provides managed servers for tenants. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names (FQDNs). A management system of the server hosting system receives a DNS data message from a tenant router in the server hosting system. The DNS data message specifies an IP address of one of the managed servers, a tenant-side FQDN for the managed server, and an IP address of the tenant router. The managed server and the tenant router are associated with a given tenant. The IP address is also an IP address of another one of the managed servers. In response, the management system obtains a management-side IP address and a management-side FQDN for the managed server. The management system then updates a Domain Name System (DNS) record to associate the management-side FQDN with the management-side IP address.

Abstract: A server hosting system provides managed servers for tenants. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names. A server manager for the server hosting system detects a deletion event for one of the managed servers. In response to detecting the deletion event, the server manager sends a web services request to a Domain Name Service (DNS) web service having a web API. The web services request requests invocation of a deregister method in the web API. The deregister method removes DNS records that associate a management-side fully qualified domain name (FQDN) for the managed server with a management-side IP address for the managed server. No other managed server in the server hosting system has the management-side IP address. No other managed server in the server hosting system has the management-side FQDN.
