Here is the current status 

First Octet Histogram
 
 Octet 224 had    529 entries or  39.21 % 
 Octet 225 had     24 entries or   1.78 % 
 Octet 226 had      7 entries or   0.52 % 
 Octet 227 had     19 entries or   1.41 % 
 Octet 228 had     72 entries or   5.34 % 
 Octet 229 had     30 entries or   2.22 % 
 Octet 230 had      9 entries or   0.67 % 
 Octet 231 had     11 entries or   0.82 % 
 Octet 233 had    499 entries or  36.99 % 
 Octet 234 had     23 entries or   1.70 % 
 Octet 235 had     14 entries or   1.04 % 
 Octet 236 had     81 entries or   6.00 % 
 Octet 237 had     16 entries or   1.19 % 
 Octet 238 had     15 entries or   1.11 % 
 
So the reserved space is being used, at the few % level.
