[44net] DNS for Belgium (44.144.0.0/16)

Hey Guys, Does anyone have any contact info for ON4SAX? He should be the maintainer for the Belgium subnets. But I'm not able to mail him through the contact info on qrz.com (on4sax@on4sax.be<mailto:on4sax@on4sax.be>) to make DNS changes for my hosts. The domain seems parked and has no MX record as far as I can see. I also saw that the range for Belgium is routed through Wireless Belgium and as such not through ucsd so I am also wondering how I can get incoming traffic from the world (non 44net) to my 44net hosts and outbound from my 44net hosts towards the world. Thanks in advance. 73, Ruben - ON3RVH
