Download standard MIB format if you are planning to load a MIB file into some system (OS, Zabbix, PRTG ...) or view it with a MIB browser. CSV is more suitable for analyzing and viewing OID' and other MIB objects in excel. JSON and YAML formats are usually used in programing even though some systems can use MIB in YAML format (like Logstash).
Keep in mind that standard MIB files can be successfully loaded by systems and programs only if all the required MIB's from the "Imports" section are already loaded.
The tree-like SNMP object navigator requires no explanations because it is very simple to use. And if you stumbled on this MIB from Google note that you can always go back to the home page if you need to perform another MIB or OID lookup.

               hh3cDhcpSnoopSpoofServerDetected 1.3.6.1.4.1.25506.2.36.2.0.1
To detect unauthorized DHCP servers on a network, the DHCP snooping device sends DHCP-DISCOVER messages through its downstream port (which is connected to the DHCP clients). If any response (DHCP-OFFER message) is received from the downstream port, an unauthorized DHCP server is considered present, and then the device sends a trap. With unauthorized DHCP server detection enabled, the interface sends a DHCP-DISCOVER message to detect unauthorized DHCP servers on the network. If this interface receives a DHCP-OFFER message, the DHCP server which sent it is considered unauthorized.
           hh3cDhcpSnoopTrapsObject 1.3.6.1.4.1.25506.2.36.2.1
               hh3cDhcpSnoopSpoofServerMac 1.3.6.1.4.1.25506.2.36.2.1.1 macaddress no-access
MAC address of the spoofing server and it is derived from link-layer header of offer packet. If the offer packet is relayed by dhcp relay entity, it may be the MAC address of relay entity.
               hh3cDhcpSnoopSpoofServerIP 1.3.6.1.4.1.25506.2.36.2.1.2 ipaddress no-access
IP address of the spoofing server and it is derived from IP header of offer packet. A tricksy host may send offer packet use other host's address, so this address can not always be trust.
