In some instances, above-mentioned source IP address may include local dns server IP address, which can use Family is input to the domain name of the targeted website of browser, when can also be transmission Email, the mail service of target e-mailbox The domain name of device.

In some instances, it when local dns server sends domain name analysis request to Authoritative DNS server, can incite somebody to action Domain name and source IP address are added in domain name mapping request message, therefore, using a kind of domain name mapping side of the embodiment of the present invention The Authoritative DNS server of method can be from the domain name after the domain name mapping request message for receiving local dns server transmission Domain name and source IP address are got in analysis request message, which can be the IP address of local dns server.

For example, user has input the domain name of " www.abc.com " in a browser, local dns server can will carry The domain name mapping request message for having the domain name and local dns server IP address, is sent to the domain name using the embodiment of the present invention The Authoritative DNS server of analytic method.The Authoritative DNS server, can be from the domain after receiving domain name mapping request message Domain name " www.abc.com " is extracted in name analysis request message and sends the local dns service of the domain name mapping request message The IP address of device.

S202, according to domain name, the inquiry domain name mapping information corresponding with domain name in presetting privately owned mapping table.

Wherein, it preserves domain name in default privately owned mapping table and domain name mapping information corresponding with domain name, domain name mapping is believed Breath includes：The corresponding parsing type of domain name analytic value corresponding with parsing type, domain name mapping information are pre-configured with and are stored in It presets in privately owned mapping table, which is the domain name of request analysis.

For example, it can preserve different web sites service by user's self-defined foundation in advance that this, which presets privately owned mapping table, The domain name mapping information of the domain name of device and corresponding Website server, alternatively, preserving the domain name of different mail server and right The domain name mapping information for the mail server answered can also preserve the domain name of different web sites server and corresponding website simultaneously The domain name mapping information of the domain name mapping information of server, the domain name of different mail server and corresponding mail server.

In some instances, when what is preserved in default privately owned mapping table is the domain name of different web sites server and corresponding net When the domain name mapping information of site server, the parsing type in the domain name mapping information can be：A (Address, address) remembers Record, CNAME (Canonical Name, canonical name) records or NS (Name Server, resolution server) records.

Analytic value may include：Website server IP address or resolution server IP address.

The domain name mapping information can also include：Website server host name, resolution server host name, domain name mapping letter It ceases life span or explanation is arranged in Website server domain name.

In some instances, when what is preserved in default privately owned mapping table is the domain name of different mail server and corresponding postal When the domain name mapping information of part server, the parsing type in the domain name mapping information can be：A (Address, address) remembers Record, CNAME (Canonical Name, canonical name) records, MX (Mail Exchanger, mail exchange) records or NS (Name Server, resolution server) it records, analytic value may include：Mail server IP address or resolution server IP address.

The domain name mapping information can also include：Mail server host name, resolution server host name, domain name mapping letter It ceases life span or explanation is arranged in mail server domain name.

It, can be in default privately owned mapping table after obtaining the domain name carried in domain name mapping request message by step S201 It is inquired, inquires domain name mapping information corresponding with domain name.

For example, as shown in table 1, table 1 is to preset privately owned mapping table to preserve the domain name of different web sites server in table 1 With the domain name mapping information of corresponding Website server, in table 1, domain name mapping information includes：Parse type, life span and Analytic value.

Such as：The domain name mapping type of " abc.com " is：A (Address, address) is recorded, and analytic value is：Website service Device IP address；Life span：3600s.

The domain name mapping type of bcd.com is：CNAME (specification name) is recorded, analytic value：Website server host name； Life span：3600s.

The domain name mapping type of cde.com is：NS (Name Server, resolution server) is recorded, analytic value：Parsing clothes Business device host name/IP address；Life span：3600s.

Table 1 presets privately owned mapping table

Domain name title	Parse type	Life span (s)	Analytic value
				abc.com	A	3600	Website server IP address
bcd.com	CNAME	3600	Website server host name
				cde.com	NS	3600	Resolution server host name/IP address

In some instances, it can be two tables that this, which presets privately owned mapping table, respectively preset top-level domain table and preset Second-level domain's famous-brand clock.As shown in table 2, may include domain name in table 2 to preset the default top-level domain table in privately owned mapping table ID (identity, identity), top-level domain and life span.Wherein, domain name ID is when establishing to preset privately owned mapping table, by applying The ID that the Authoritative DNS server of the domain name analytic method of the embodiment of the present invention generates can be used for distinguishing different domain names.

Table 2 presets the default top-level domain table in privately owned mapping table

Domain name ID	Top-level domain	Life span (s)
			0102202	abc.com	86400
0102203	bcd.com	86400
			0102204	cde.com	86400
