### Description

```asn1
ipMcastRouteSource OBJECT-TYPE
SYNTAX InetAddress
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The network address which, when combined with the
corresponding value of ipMcastRouteSourcePrefixLength,
identifies the sources for which this entry contains
multicast routing information.
This address object is only significant up to
ipMcastRouteSourcePrefixLength bits. The remaining address
bits are set to zero. This is especially important for this
index field, which is part of the index of this entry. Any
non-zero bits would signify an entirely different entry.
For addresses of type ipv4z or ipv6z, the appended zone
index is significant even though it lies beyond the prefix
length. The use of these address types indicate that this
source address applies only within the given zone. Zone
index zero is not valid in this table."
```

**Classification:** MIB object for network management
