[AusNOG] New /21 on Bogan / Delinquent Lists

[Elly Tawhai]

Dear Nathan,

While APNIC tries its best to allocate clean blocks, as the free pool of 
IPv4 address space reaches exhaustion it is becoming harder to prevent 
connectivity problems such as what you're currently experiencing from 
happening.

We understand that this is an important issue for the community; and as 
such, we do take action to minimize any problems that may result.

We are currently investing extra resources to extend our debogon testing 
inline with the increase in demand, and in communications and education 
campaigns to better inform the community of this potential problem.

I will be in touch to see how I can further assist you.

Regards,
Elly
