If you want to learn from my past fumbling -- I register everything with SNDS and JMRP as /24 (or smaller), nothing bigger. Once upon a time I found that sometimes it seemed to treat a submission as though it were only a /24 even though it was a larger range (/18 or /20). That may/may not still be an issue, I have no idea, since long ago I decided to treat every range as if it were /24 or smaller. Which means you'd be entering it as 64 /24s instead of one /18, if I did my math correctly. Fun? No. Does it work? Yes...I've not had any sort of issue with JMRP for a long time.
(Well, I've had two unrelated issues with JMRP periodically, not related to this. One is, sometimes when we give a client access to SNDS data, they try to modify the JRMP settings for a range. We warn clients that we monitor for this and revoke access of anybody caught doing this. Two, Proofpoint seemed to be eating new SNDS access verification requests, but only for a new range in RIPE. Never figured out why only those ranges were affected, but we were able to whitelist around it.) You might have a hard time finding somebody at MS who can actually assist with an SNDS/JMRP issue. Good luck! BTW, treating all your ranges as /24 makes doing IP allocation math and feeding ranges to other services more simple, too. I now do it for all ISP FBLs and registrations (CSA, WP.pl,. JMRP, Return Path multi-FBL, etc.) and it means I no longer have to think about CIDR in sizes other than /24 (and I don't have to worry about somebody else being able to do the math, either).
