Abstract

The present invention provides a computer implemented method for resolving a universal resource identifier (URI). The client computer receives the universal resource identifier, which is comprised of a domain name. The client computer looks up a row corresponding to the domain name in a domain specific domain name service (DNS) server list. The row includes at least a first internet protocol address. The client computer transmits a domain name service (DNS) query addressed to the first internet protocol address responsive to looking up the row. Upon receiving a valid response in at least one packet, wherein the at least one packet is from the first internet protocol address, the client computer resolves the universal resource identifier to a second internet protocol address.

Claims

receiving, at the mobile device, a valid response in at least one packet, wherein the at least one packet is from the first internet protocol address; and

resolving, by the mobile device, the universal resource identifier to a second internet protocol address.

2. The computer implemented method of claim 1, wherein looking up comprises:

looking up a row based on a second level domain name, wherein the second level domain is present in a row of the domain specific domain name service server list.

3. The computer implemented method of claim 1, wherein the row contains the first internet protocol address, and the first internet protocol address is not present in a default domain name service (DNS) server row.

4. The computer implemented method of claim 1, wherein resolving comprises:

receiving the second internet protocol address from a device corresponding to the first internet protocol address; and

transmitting an internet request addressed to a second device corresponding to the second internet protocol address.

5. The computer implemented method of claim 1, wherein a valid response comprises:

receiving a packet containing the second internet address within a predetermined time after transmitting the domain name service (DNS) query.

6. The computer implemented method of claim 1, further comprising:

terminating an authenticated session to the private domain; and

removing the row corresponding to the private domain from the domain specific domain name service (DNS) server list in response to terminating.

7. The computer implemented method of claim 1, wherein adding comprises:

receiving the first internet protocol address from a dynamic host configuration protocol (DHCP) server in response to logging in.

8. A computer program product for resolving a universal resource identifier (URI) the computer program product comprising:

a computer-usable, storage device having computer-usable program code embodied therewith, the computer program product comprising;

computer-usable program code configured to log in to a private domain;

computer-usable program code configured to add a row corresponding to a domain to a domain specific domain name service (DNS) server list in response to logging in;

computer-usable program code configured to receive by a mobile device the universal resource identifier, the universal resource identifier comprising a domain name;

computer-usable program code configured to look up a row, by the mobile device, wherein the row corresponds to the domain name in a domain specific domain name service (DNS) server list, the row comprising a first internet protocol address, the domain specific domain name service (DNS) server list comprising the row and a general purpose row, wherein the general purpose row does not correspond to any single domain name, wherein the general purpose row is a row that has only Internet protocol addresses that correspond to general purpose DNS servers, wherein the domain specific domain name service (DNS) server list is internal to the mobile device, and wherein the domain specific domain name service (DNS) server list comprises at least one Internet protocol address for a domain specific DNS server;

computer-usable program code configured to transmit, from the mobile device, a domain name service (DNS) query addressed to the first internet protocol address responsive to looking up the row;

computer-usable program code configured to receive, at the mobile device, a valid response in at least one packet, wherein the at least one packet is from the first internet protocol address; and

computer-usable program code configured to resolve, by the mobile device, the universal resource identifier to a second internet protocol address.

9. The computer program product of claim 8, wherein computer usable code to look up comprises:

computer usable program code configured to look up a row based on a second level domain name, wherein the second level domain name is present in a row of the domain specific domain name service server list.

10. The computer program product of claim 8, wherein the row contains the first internet protocol address and the first internet protocol address is not present in a default domain name service (DNS) server row.

11. The computer program product of claim 8, wherein computer usable program configured to resolve comprises:

computer usable program code configured to receive the second internet protocol address from a device corresponding to the first internet protocol address; and

computer usable program code configured to transmit an internet request addressed to a second device corresponding to the second internet protocol address.

12. The computer program product of claim 8, wherein computer usable program code configured to receive a valid response comprises:

computer usable program code configured to receive a packet containing the second internet address within a predetermined time after transmitting the domain name service (DNS) query.

13. The computer program product of claim 8, wherein computer program product further comprises:

computer-usable program code configured to terminate an authenticated session to the private domain; and

computer-usable program code configured to remove the row corresponding to the private domain from the domain specific domain name service (DNS) server list in response to terminating.

14. The computer program product of claim 8, wherein computer-usable program code configured to add comprises:
