Specific embodiment
In order to make those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
The embodiment of a part of the invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
The model that the present invention protects all should belong in member's every other embodiment obtained without making creative work
It encloses.
Description and claims of this specification and term " first ", " second ", " third " and " in above-mentioned attached drawing
Four " etc. are not use to describe a particular order for distinguishing different objects.In addition, term " includes " and " having " and it
Any deformation, it is intended that cover and non-exclusive include.Such as it contains the process, method of a series of steps or units, be
System, product or equipment are not limited to listed step or unit, but optionally further comprising the step of not listing or list
Member, or optionally further comprising other step or units intrinsic for these process, methods, product or equipment.
Below in conjunction with drawings and examples the present invention will be further explained explanation.
Fig. 1 is that the domain name analytic method first of the Intelligent set top box for the hybrid channel IPV4 and IPV6 of the invention is implemented
The flow chart of example；As shown in Figure 1, the domain name mapping of the Intelligent set top box provided by the present invention for the hybrid channel IPV4 and IPV6
Method the following steps are included:
S11, Intelligent set top box initiate to request by domain name to dns server；
S12, the dns server are according to the corresponding IPv4 source address of request return domain name and the source IPv6
Location；
S13, the Intelligent set top box are initiated by the IPv4 source address or the IPv6 source address to destination server
Request of data；
S14, the destination server are returned the result according to the request of data.
In step s 11, user uses the IPv6 Address requests order program service to be accessed of the machine in Intelligent set top box
Domain name is sent to dns server by the domain name of device, Intelligent set top box.
In step s 12, after dns server receives domain name, IPv4 source address corresponding with the domain name and the source IPv6 are inquired
Address.Specifically, the IPv4 source address and the IPv6 source address are the return address DHCP.DHCP(Dynamic Host
Configuration Protocol, dynamic host configuration protocol) it is generally applied in large-scale LAN environment, mainly
Effect be concentrate management, distribution IP address, make the host in network environment dynamically obtain IP address, the address Gateway,
The information such as dns server address, and it is able to ascend the utilization rate of address.
In step s 13, first, it is determined that whether IPv6 network environment is connected to；If connection, using the source IPv6
Request of data is initiated to the destination server in location；If be not connected to, use the IPv4 source address to the purpose service
Device initiates request of data.Specifically, after Intelligent set top box receives IPv4 source address and IPv6 source address, first using the source IPv6
Request of data is initiated to the destination server in location, if request failure, then it represents that IPv6 network environment is obstructed, in IPv6 network
When environment is obstructed, request of data is initiated to the destination server using the IPv4 source address.
In step S14, if Intelligent set top box initiates data to the destination server by the IPv6 source address
Request, then the destination server returns to corresponding result according to the request of data；Correspondingly, if Intelligent set top box passes through
The IPv4 source address initiates request of data to the destination server, then the destination server is returned according to the request of data
Return corresponding as a result, and using IPv4 Address requests data always before the expired update of subsequent dns.
First in the domain name analytic method of the Intelligent set top box for the hybrid channel IPV4 and IPV6 of the invention implements
In example, user requests domain name in set-top box, and dns server returns to the corresponding IPv4 source address of the domain name and IPv6 source address；
Then, if server returns the corresponding address IPv6, show that the IPv6 network between set-top box and dns server is to connect
Logical, in the case where IPv6 network-in-dialing, request of data preferentially is initiated to destination server using IPv6 source address；If
Dns server does not return to the corresponding address IPv6, then shows that the IPv6 network between set-top box and dns server is not to be connected to
, in the disconnected situation of IPv6 network, request of data is initiated to destination server using IPv4 source address.Thus, it is possible to
Solve the domain name mapping problem in the case where hybrid channel IPV4 and IPV6, between Intelligent set top box and dns server.
Second in the domain name analytic method of the Intelligent set top box for the hybrid channel IPV4 and IPV6 of the invention implements
In example, further include the steps that judging whether DNS updates, is initiating data to the destination server using the IPv4 source address
It when request, first determines whether DNS updates, if do not updated, is sent out using the IPv4 source address to the destination server
Play request of data；If updated, rejudge whether IPv6 network environment is connected to by above method.
Fig. 2 is the principle of the domain name analysis system of the Intelligent set top box for the hybrid channel IPv4 and IPv6 of the invention
Figure；As shown in Fig. 2, the domain name analysis system of the Intelligent set top box for the hybrid channel IPv4 and IPv6 of the invention is connected to intelligence
It can be between set-top box and dns server, comprising:
Request sending module 110 is initiated to request by domain name for Intelligent set top box to dns server；
Source address return module 120 returns to the corresponding IPv4 of domain name according to the request for the dns server
Source address and IPv6 source address；
Request of data sending module 130 passes through the IPv4 source address or the source IPv6 for the Intelligent set top box
Request of data is initiated to the destination server in address；
Result return module 140 is returned the result for the destination server according to the request of data.
Specifically, the IPv4 source address and the IPv6 source address are the return address DHCP.
Specifically, the request of data sending module 130 includes:
Judging result for judging whether IPv6 network environment is connected to, and is sent to transmission unit by the first judging unit；
Transmission unit, for initiating request of data to the destination server according to the judging result, wherein in IPv6
When network environment is connected to, request of data is initiated to the destination server using the IPv6 source address, in the IPv6 network
When environment is not connected to, request of data is initiated to the destination server using the IPv4 source address.
Specifically, the request of data sending module further include:
Second judgment unit, if the DNS updates, sends first control signal extremely for judging whether DNS updates
First judging unit rejudges whether IPv6 network environment is connected to by first judging unit, if the DNS is not
Update, then send second control signal to the transmission unit, from the transmission unit using the IPv4 source address to described
Destination server initiates request of data.
