I highlighted the part of most interest, which appears to be a block suballocated to someone using the email address email@example.com.
I took a look at the sites hosted in this /24 and these are the results [csv]. There are 37 malicious websites (identified by Google) out of 185 that I found in this network range. The usual level of badness tends to be around 1%, but here it is 20%. Looking at the domains, it appears that there is nothing at all of value here and you can probably count them all as malicious.
