Embodiment Construction

[0048] Step 102: Screen the DNS protocol network session data according to the set source IP and communication type.

[0062] Step S02: filtering and screening data, and performing conditions according to source IP conditions and communication types to obtain data set 2.

[0064] Step S03: in the data set 2, for each source IP, the indicator 1 of the source IP is calculated separately: DNS request network

[0074] Step S09: Determine one by one whether there is an intersecting interval between each source IP and each time starting interval of a plurality of target IPs.

[0095] It should be noted that although the operations of the method of the present invention are described in the drawings in a particular order, this is not intended to

[0097] The unit, device or module, etc. described in the above-mentioned embodiments may be specifically implemented by a computer chip or entity, or

Abstract

The embodiment of the present application discloses a domain name server DNS resolution server address collection method, system, device and readable storage medium. By screening the DNS protocol network session data within the set time range in the system environment, the filtered DNS is determined. The number of target IPs associated with each source IP in the protocol network session data, judge whether the first index of each source IP meets the first preset condition one by one, and determine the first index of each source IP in the DNS protocol network session data after screening. Two indicators, judge whether the second indicator of each source IP satisfies the second preset condition one by one; calculate the time interval of DNS request network session between each source IP and target IP in the DNS protocol network session data after filtering respectively, to obtain The target IP marked as the DNS resolution server is deduplicated to obtain the address set of the target DNS resolution server. Data processing is carried out from the network layer traffic of the system environment, and then the DNS resolution server address set in the system environment is obtained, which is simple and efficient.

Description

A method and system for collecting addresses of DNS resolution servers technical field Embodiments of the application relate to the technical field of network communication data analysis, processing and detection, and in particular to a kind of DNS solution. Analysis server address collection method, system, device and readable storage medium. Background technique DNS (Domain Name Server, domain name server) is to carry out domain name and corresponding IP address conversion server. A domain name and the corresponding IP address are stored in the DNS to resolve the domain name of the message. [0003] The DNS is also carried by a specific server, so it also has an IP address, that is, the DNA resolution server address. In network management and maintenance, it is necessary to collect the DNS resolution server addresses set by internal hosts. The traditional method is Manual collection or collection by physical detection equipment, manual collection is to check the D...
