Last week I saw an interesting post at APNIC mailing list about IRINN (recently formed NIR in Indian region). 

Poster Jimmy was concerned about IRINN’s netname

inetnum: 0.0.0.0 - 255.255.255.255  
netname: IRINN-BROADCAST-ADDRESSES  
descr: Broadcast addresses  
descr: These addresses cannot (should not) be routed on the Internet.  
country: IN  
admin-c: IH1-IN  
tech-c: IH1-IN  
status: ALLOCATED PORTABLE  
remarks: send spam and abuse report to info@irinn.in  
mnt-by: IRINN-HM  
mnt-irt: IRT-IRINNHM-IN  
mnt-lower: IRINN-HM  
changed: hostmaster2@irinn.in 20130420  
source: IRINN

As per first two lines entire IPv4 address space i.e 0.0.0.0/0 (ranging from 0.0.0.0 to 255.255.255.255) was put as IRINN-Broadcast while expected was IANA broadcast (since IANA sits on top in this RIR & NIR hierarchy).
