For what it's worth:

Host script results:
|_ asn-query: No Such Name
|  whois: Record found at whois.arin.net
|  netrange: 204.152.64.0 - 204.152.65.255
|  netname: PRIV-HADF2
|  orgname: Sun Microsystems, Inc.
|  orgid: SSMIB
|_ country: US stateprov: CA

Looks like it's not routed and there's a seemingly current doc for Sun's
Ultra Enterprise Cluster HA 1.3 that mention these two Class C's:
