Abstract

Disclosed are methods, circuits, devices, systems and associated computer executable code for providing Domain Name Resolution functionality to data client device accessing network data through an access point. According to some embodiments, an access point may be integral or otherwise functionally associated with a zone specific domain name system (ZSDNS, which ZSDNS may include a local cache of DNS records, which local cache of DNS records may be zone specific.

Claims

1. A zone specific domain name system (ZSDNS) associated with an access point of a data access network, said system comprising:

a DNS query detector to detect DNS queries to a remote DNS server submitted by a data client device through said access point;

control logic circuitry to search a local DNS cache for records relevant or responsive to the submitted query while allowing the submitted query to pass to the remote DNS server; and

a DNS query responder to respond to the DNS query of the data client device in the event records relevant or responsive to the submitted query are identified in said local cache.

2. The system according to claim 1, further comprising a local DNS database cache updater to update said local cache with information from a response received from the remote DNS cache.

3. The system according to claim 2, wherein updating includes amending a record of the local DNS cache.

4. The system according to claim 2, wherein updating includes appending new records to the local DNS cache.

5. A method of providing zone specific domain name system (DNS) services on a data access network having access points, said method comprising:

detecting a DNS query to a remote DNS server submitted by a data client device through an access point;

searching a local DNS cache for records relevant or responsive to the submitted query while allowing the submitted query to pass to the remote DNS server; and

responding to the DNS query of the data client device in the event records relevant or responsive to the submitted query are identified in the local cache.

6. The method according to claim 5, further comprising updating a local cache with information from a response received from the remote DNS cache.

7. The method according to claim 6, wherein updating includes amending a record of the local DNS cache.

8. The method according to claim 6, wherein updating includes appending new records to the local DNS cache.

9. A data access network comprising:

a set of access points to provide network access to data client devices; and

a zone specific domain name system (DNS) associated with one or more of said access points and comprising;

a DNS query detector to detect DNS queries to a remote DNS server submitted by a data client device through said access point;

control logic circuitry to search a local DNS cache for records relevant or responsive to the submitted query while allowing the submitted query to pass to the remote DNS server; and

a DNS query responder to respond to the DNS query of the data client device in the event records relevant or responsive to the submitted query are identified in said local cache.
