[AfrIPv6-Discuss] Need of help for scaning ipv6 block

[JORDI PALET MARTINEZ]

I can point to the authors of a similar study in LACNIC (in copy).

 

https://labs.lacnic.net/Identificando-servidores-DNS-IPv6-Open-Resolvers/

 

The article mentions as well a similar study in RIPE. Sorry is Spanish!

 

I think the point is to go from the “reverse root server” administered by Afrinic, so you don’t need to do a complete scanning, which will be near to impossible …

 

This was also presented in the LACNIC31: https://www.lacnic.net/3636/50/evento/agenda-lacnic-31#thursday-ftl

 

Look for the slides and video:

 

Identifying Open Resolvers in IPv6

I’m sure they will be able to help!

My objective for this study is to detect open DNS resolvers in the AFRINIC IP space.

Hi Malick,

 

That’s somehow, one of the “advantages” of IPv6, that make it much more difficult.

 

If the operators and end-users are doing a good work, they will not be assigning neither contiguous prefixes, neither contiguous prefixes/LANs, neither contiguous hosts!

 

May be if you explain a bit more what you’re trying to achieve, we can give some ideas.

 

Regards,

Jordi

Good morning, everyone!
I'm doing a study on afrinic's IP address blocks. I didn't have any constraints with ipv4 address blocks. The use of the zmap tool allowed me to do a quick scan on all available IPV4 addresses. Unfortunately, i don't know how to scan IPV6 blocks without taking a long time. Nmap, can help me, but it could take several years to finish. Zmap or Masscan don't support ipv6. 

I would like to know if anyone has a solution to quickly scan ipv6 address blocks to identify ipv6 servers that offer a service.

 

Thanks for your help!
