I'm not that familiar with emule (a file trading program I presume), so I'm not sure what to suggest ... with that said, does the filter indicate exactly what IP address(es) are being blocked - that would be more helpful than an IP range, which can be quite large...

Note the ARIN information that mentions MoreVisibility.com is out of date - they appear to have been delegated the IP range (a portion of which we are now in) at one time in the past; they're still hosted with RackSpace elsewhere.

Be aware tracert has numerous limitations ... one of which is most tracert programs will resolve only one IP (often at random) for the domain entered regardless of how many IPs are associated with the particular domain ... cannabis.com homepage is mirrored, so you'll need need to put in 209.61.129.146 into your whitelist too - also the boards here are on 69.20.47.161 and thus should be added as well.

IPs are subject to change at any time so IP whitelists/blocklists need to be reviewed regularly for changes.
