GeoIPASNum Generator

MaxMind's version of ASN database doesn't include overriden description (e.g. 27.100.36.0/24) or CIDRs that are announced by multiple ASNs (e.g. 63.223.97.0/24).

This set of scripts will get ASNs from bgp.he.net and generate (legacy) MaxMind format GeoIPASNum.dat.

How to use

1. Run bash ./new.sh to generate all ASNum list and save to asn.txt.
2. Start your socks5 proxies starting from port 60000 (60000, 60001, ...), modify TCNT in asn_generator.py to the proxies you have.
3. Run python ./asn_generator.py. This will generate GeoIPASNumC.csv and GeoIPASNumCv6.csv
4. Run cat GeoIPASNumC.csv |sort -n|uniq > GeoIPASNum1.csv
5. Run cp GeoIPASNum1.csv GeoIPASNum1v6.csv && cat GeoIPASNumCv6.csv |sort -n|uniq >> GeoIPASNum1v6.csv
6. Run python ./asn_sort.py. This will generate GeoIPASNum2.csv
7. Run python ./asn_sort.py ipv6. This will generate GeoIPASNum2v6.csv
8. Run python ./csv2dat.py -w GeoIPASNum2.dat mmasn GeoIPASNum2.csv. This will generate GeoIPASNum2.dat
9. Run python ./csv2dat.py -w GeoIPASNum2v6.dat mmasn6 GeoIPASNum2v6.csv. This will generate GeoIPASNum2v6.dat
10. Run bash ./svg.sh, bash ./svg6.sh and bash ./flags.sh to download other resources.

Note

• GeoIPASNum2.dat is a IPv4 only version, GeoIPASNum2v6.dat supports both IPv4 and IPv6.
• csv2dat.py is stolen from mteodoro/mmutils.
• The function to bypass browser test for bgp.he.net is deleted to prevent from bad guys XD. You should figure how it works and implement it in ccbypass of asn_generator.py.
• asn_sort.py will combine ASN descriptions if they have same CIDR. If there's containing relation, it will substrate smaller block from bigger block.
• Files are cached in html folder and will expire in 5 days.
