How to obtain the latest IP segments of China Telecom, China Netcom, and China tietong

APNIC is an organization that manages IP Address Allocation in the Asia Pacific region. It has a rich and accurate IP Address Allocation library, and this information is also made public to the public! Next let's take a look at how to obtain the IP address distribution of some telecom operators in Linux:

Wget http://ftp.apnic.net/apnic/dbase/tools/ripe-dbase-client-v3.tar.gz

Tar xzvf ripe-dbase-client-v3.tar.gz
CD whois-3.1
./Configure
Make
After completing the above compilation and installation, we start to get the IP address segment;

China Netcom:
./Whois3-H whois.apnic.net-l-I MB MAINT-CNCGROUP>/var/CNC

China Telecom:
./Whois3-H whois.apnic.net-l-I MB MAINT-CHINANET>/var/Chinanet

China tietong:
./Whois3-H whois.apnic.net-l-I MB MAINT-CN-CRTC>/var/CRTC

When you open the obtained file, you can see that the information in it is very detailed, and even the owner, phone number, email, and other information of each branch. If you want to get a neat and clean IP address segment file, simply use grep and awk for simple filtering.

Filter and extract IP segments

China Netcom:
Sed-e '/./{H; $! D;} '-e' X;/cncgroup /! D'/var/CNC | grep 'inetnum'>/var/cnc.txt

China Telecom:
Sed-e '/./{H; $! D;} '-e' X;/Chinanet /! D'/var/Chinanet | grep 'inetnum'>/var/chinanet.txt

China tietong:
Sed-e '/./{H; $! D;} '-e' X;/CN-CRTC /! D'/var/CRTC | grep 'inetnum'>/var/crtc.txt

I also checked on the Internet and someone provided the following: (download IP segment finder, IP segment query software, IP segment scanner, and IP segment search), but I think it is not a good reason, because none of them are the latest.
Foreign IP segment such as [U. S. IP segment, South Korea IP segment, Japan IP segment, the latest U. S. IP segment, IP segment of Japan,] please go to the http://ftp.apnic.net to query
