Abstract
In embodiments of the present invention improved capabilities are described for accessing a DNS server, where the DNS server may be a DNS server within the control of a administrator. A pair of name and IP address may be stored on the DNS server. A client may then transmit the name to a DNS server to request the DNS server to lookup the IP address related to the client transmitted name. This client to DNS server communication may be performed as part of a network request from the client. The IP address may then be returned to the client in response to the connection request, which may allow the client to interpret the return of the security IP address as an indication of a known DNS server and therefore a known network. As a result, the client may then be able to set its security rules according to known network rules. Further, the identifying of a known network may be associated with location information associated with the DNS server, and thus the client, where the location information may be associated with multiple DNS IP address entries.
