[anti-abuse-wg] weird ERX networks ?

Hi,

we receive Spam from some networks we cannot find any whois record for.

An example:
62.61.196.0
(we found about 1000 networks like this)


ARINs whois says, its RIPE
RIPEs whois says, its AFRINIC
LACNIC also says, its AFRINIC

but AFRINICs whois says, its "world-wide" ...


So, where is this really allocated too and where can we we find a whois 
record for those networks ?
Unallocated, but still in use from somebody ?
Anybody an idea ?

Here are the whois records:

ARIN:
NetRange:       62.0.0.0 - 62.255.255.255
CIDR:           62.0.0.0/8
OriginAS:
NetName:        RIPE-C3
NetHandle:      NET-62-0-0-0-1


RIPE:
inetnum:      62.61.192.0 - 62.61.255.255
org:          ORG-AFNC1-RIPE
netname:      AFRINIC-NET-TRANSFERRED-20050223
descr:        This network has been transferred to AFRINIC
remarks:      These IP addresses are assigned in the AFRINIC region.


AFRINIC:
inetnum:      0.0.0.0 - 255.255.255.255
netname:      IANA-BLK
descr:        The whole IPv4 address space
country:      EU # Country is really world wide
org:          ORG-IANA1-AFRINIC




Kind regards, Frank
