Hi Nanog

I'm curious.

I have been receiving some major ssh brute-force attacks coming from random
hosts in the 116.8.0.0 - 116.11.255.255 network. I have sent a complaint to
the e-mail addresses obtained from a whois query on one of the IP Addresses.

My e-mail bounced back from both recipients. Once being rejected by filter
and the other because the e-mail address doesn't exist. I would have
thought that contact details are rather important to be up to date, or not?

Besides just blocking the IP range on my firewall, I was wondering what
others would do in this case?


$ host -t txt 0.0.8.116.abuse-contacts.abusix.org
0.0.8.116.abuse-contacts.abusix.org descriptive text "18977164171 () 189 cn"

However, I don’t see an mnt-irt: field which is mandatory for APNIC records updated/created after 2010 (unfortunately 
this object was last updated in 2007). So I would start by pointing to APNIC that no such entry exist and as this 
network is of importance for the community, the addition of an abuse/IRT POC would be beneficial for everyone and if 
they could help, this would be greatly appreciated.

But that’s the theory...
