How to query the number of websites on an IP address

Query the number of domain names bound to an IP address. Generally, the second-level domain name is not queried.
Main purposes:
1. query before a host is rented, such as oversales.
2. Search for some websites of interest, so that multiple websites of the same person can be easily queried.
3. Satisfy gossip Psychology
4. Others

Currently, the following services are available:
1. myipneighbors, with a verification code and no other query restrictions;
2. iwebtool. If it is not registered, You can query it five times in an hour;
3. whosonmyserver, unrestricted; Use discountedscriptsCode, You can also use discountedscripts demos to query;
4. http://www.domaintools.com/reverse-ip/. for a finite query, you can provide the number and the first three domain names;

Query quality analysis:
These scripts cannot guarantee the integrity of the query results, that is, some results are missing. Take this blog domain name as an example. The above query numbers are:

No.	Name	Numbers
1	Myipneighbors	14
2	Iwebtool	1
3	Whosonmyserver	14
4	Domaintools	22
5	IP-Domain	14
6	Webhosting	33
7	Yougetsignal	14

In addition, the query for domestic virtual hosts is relatively effective due to the limited number of domestic IP addresses. For foreign virtual hosts, the query is not effective due to technical and IP address-rich reasons, for reference only.
