SNMP OID Lookup is a free browser-based reference tool for searching common SNMP Object Identifiers (OIDs) by name, numeric dotted string, or MIB object. Enter a value like 1.3.6.1.2.1.1.3.0 or sysUpTime and the tool returns the matching object's name, dotted-decimal OID, the MIB it belongs to (such as SNMPv2-MIB, IF-MIB, or HOST-RESOURCES-MIB), its syntax type (INTEGER, Counter32, Gauge32, TimeTicks, OCTET STRING), and a plain-language description of what the value represents.
It is used by network engineers, NOC operators, and monitoring administrators who configure polling in tools like Zabbix, LibreNMS, PRTG, or SolarWinds and need to confirm which OID maps to interface traffic counters, system descriptions, uptime, or CPU load before adding it to a template.
SNMP organizes every manageable value into a hierarchical tree called the Management Information Base (MIB). Each node has an Object Identifier, written as a sequence of integers separated by dots that traces a path from the root down to the object. For example, 1.3.6.1.2.1.1.3.0 decodes as iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).system(1).sysUpTime(3).0, where the trailing .0 is the instance for a scalar object. This tool maps between the human-readable object names and these numeric paths so you do not have to load raw MIB files to identify a value.
Most common objects live under the mib-2 subtree (1.3.6.1.2.1), while vendor-specific objects live under the enterprises branch (1.3.6.1.4.1) followed by an IANA-assigned enterprise number. The syntax type shown matters when polling: Counter32 and Counter64 values only ever increase and wrap around, so monitoring systems must compute the delta between two polls (rate = (value2 - value1) / (t2 - t1)) rather than reading them directly. Gauge32 values, by contrast, represent an instantaneous reading such as current bandwidth, and TimeTicks are counted in hundredths of a second.
A MIB is a definition file that describes a group of related managed objects, while an OID is the specific numeric address of one object within the overall tree. This tool shows both, mapping each OID to the MIB module that defines it.
A trailing .0 marks a scalar object with a single instance, such as sysName.0. Objects that are rows in a table (like ifDescr in the interfaces table) are indexed by a value such as the interface number instead, for example ifDescr.2.
This tool focuses on common standard OIDs from widely used MIBs such as SNMPv2-MIB, IF-MIB, IP-MIB, and HOST-RESOURCES-MIB. Vendor objects under the enterprises branch (1.3.6.1.4.1) require the specific vendor MIB, which you can identify by the enterprise number in the OID.
Copy the dotted OID and use it with a command like snmpget or snmpwalk, for example snmpwalk -v2c -c public 192.0.2.1 1.3.6.1.2.1.2.2.1.10, or paste it into the custom OID field of your monitoring platform.
No. It is a pure reference lookup that matches your input against a database of known OIDs. It does not send any SNMP traffic, so it cannot read live values from a router or switch.
Yes, it is completely free with no sign-up. Lookups run in your browser against a static OID reference, so the OIDs you search are not stored on a server or shared with third parties.
The OID numbering is the same across SNMPv1, v2c, and v3. The version you choose affects authentication and message format, not the OID address of an object, so a listed OID works regardless of which version your device supports.
