[SC-Help] Spam from IANA space or forged

[David Butler]

SC says this is from IANA space and wants to devnull it. WHen I manually
parse the IP it is indeed in an IANA range:

NetRange:   73.0.0.0 - 79.255.255.255
CIDR:       73.0.0.0/8, 74.0.0.0/7, 76.0.0.0/6
NetName:    RESERVED-7
NetHandle:  NET-73-0-0-0-1
Parent:
NetType:    IANA Reserved

Is this really where the spam came from or is this a forgery that fooled the
SC engine ?
