SNMP

Hi, I have a snmp oid for virtual server which is SMI::enterprises.3375.2.2.10.2.3.1.12.33.47.67.111.109.109.111.110.47.68.78.83.95.51.57.95.116.99.112.95.118.105.114.116.117.97.108.95.115.101.114.118.101.114 = Gauge32: 0

3375.2.2.10.2.3.1.12 --> oid .47.67.111.109.109.111.110.47.68.78.83.95.51.57.95.116.99.112.95.118.105.114.116.117.97.108.95.115.101.114.118.101.114 --> full path of VS

I could not understand what 33 is between asteriks?
