PHP domain name resolution information query web version gadget v2.0

The web version of the php domain name resolution information query tool can check the IP of domain name resolution, as well as resolution records such as A, CNAME, MX, NS, TXT, AAAA, and SRV.

It is a must-have practical tool for webmasters and technicians who use domain names. It can be used quickly by accessing the URL.

It is recommended to use this source code in the Linux platform php5.4-5.6 environment. I also use it normally under ngnixapache under windows.

Meaning:

Instantly query domain name resolution information (not cached locally).

1. Parse IP/A/Cname: used by website administrators to determine whether the parsing is effective.

2.MX: Can be used to determine whether the mailbox is valid to reduce the rate of invalid mailboxes.

3.TXT: Commonly used for website owner authentication, such as Tencent domain name mailbox owner authentication.

5. Part of the analysis uses load balancing or CDN acceleration, etc. The query results are for reference only.
