SNOOPING DNS MESSAGES IN A SERVER HOSTING SYSTEM PROVIDING OVERLAPPING ADDRESS AND NAME SPACES |
摘要 |
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. |
