This looks pretty intentional to me.  From
http://www.cogentco.com/en/network/looking-glass:

BGP routing table entry for 104.31.18.30/32, version 611495773
Paths: (1 available, best #1, table Default-IP-Routing-Table)
  Local
    10.255.255.255 (metric 10177050) from 154.54.66.21 (154.54.66.21)
      Origin IGP, metric 0, localpref 150, valid, internal, best

Call it a "hunch" but I doubt 10.255.255.255 is a valid next-hop router.
