Using Python to implement IP anti-search domain names

0x00

Take advantage of the summer Kungfu, the first time to learn Python, the biggest feeling is that this language is the best language I have ever seen. Especially its powerful class library and simple syntax.

I have nothing to do, today I write a small ip in Python to check the domain name tool.

IP counter-Search is the IP address of the reverse query the binding on this IP all the domain name information (a server can have more than one virtual host).

The idea is to use the Internet IP reverse search domain name site, here I use is http://dns.aizhan.com/. The query results are extracted from the Web page through a crawler and finally exported to an HTML file.

Use is also very convenient, such as you want to query the IP address is 10.10.10.10, then submit: http://dns.aizhan.com/?q=10.10.10.10 can.

However, the query results are not returned directly, but are dynamically obtained using AJAX. Then use Firebug to find the corresponding interface on the line.

The first URL is to get a total query result (JSON), the other URL is to get the title of the domain name. In this way, there are only two things to do:

The first is to extract all the URLs on this page from JSON.

The second is based on the list of URLs to find each URL corresponding to the title

The above image is a domain name corresponding to a title, just the two information as a data element can be.

With the above analysis basis, you can see my code directly.

#coding =utf-8 ' ' IP anti-search gadget http://dns.aizhan.com/index.php?r=index/domains&ip=202.203.208.8&page=1&_=  1408264478284 ' Import requests,json,urllib,sys,os from BS4 import BeautifulSoup #获取页面内容 def getpage (ip,page): R = 
Requests.get ("http://dns.aizhan.com/index.php?r=index/domains&ip=%s&page=%d"% (ip,page)) return R #获取最大的页数
    def getmaxpage (IP): R = GetPage (ip,1) json_data = {} Json_data = R.json () Maxcount = Json_data[u ' Conut '] maxpage = int (int (maxcount)/20) + 1 return maxpage #获取域名列表 def getdomainslist (IP): maxpage = GetMaxPage (i 
    p) result = [] for x in Xrange (1,maxpage+1): R = GetPage (ip,x) result.append (R.json () [U "domains"]) Return result #获取最终结果, in the form of: {URL title} and written to the file Def getresultwithtitle (filepath,domain_list): F = open (filepath, "a
        ") res_dict = {' domain ': ', ' title ': '} res_list = [] f.write ('

The above code I have carried through, the effect is as follows:





It seems that making good use of Python can really solve a lot of problems easily.
