application-wide types includes Gauge32 this wraps for counters that wrap in less than one hour with only 32 bits Extended UTCTime, to allow dates with four-digit years
(Note that this definition of ExtUTCTime is not to be IMPORTed by MIB modules.) this doesn't wrap indistinguishable from INTEGER, but never needs more than
32-bits for a two's complement representation in network-byte order (this is a tagged type for historical reasons) names of objects
(Note that these definitions of ObjectName and NotificationName are not to be IMPORTed by MIB modules.) syntax of objects the "base types" defined here are:
3 built-in ASN.1 types: INTEGER, OCTET STRING, OBJECT IDENTIFIER
8 application-defined types: Integer32, IpAddress, Counter32, Gauge32, Unsigned32, TimeTicks, Opaque, and Counter64
note that SEQUENCEs for conceptual tables and rows are not mentioned here... for backward-compatibility only built-in ASN.1 types INTEGERs with a more restrictive range may also be used includes Integer32
OCTET STRINGs with a more restrictive size may also be used hundredths of seconds since an epoch an unsigned 32-bit quantity indistinguishable from Gauge32 definitions of administrative identifiers A value used for null identifiers. the path to the root "iso" = 1 transport domains transport proxies module identities
