Yes.
It *must* be considered as an OCTET STRING.

No.
An IPv4 address is a fixed-length *binary* string,
not a (variable-length) printable string.
See RFC 2578, section 7.1.5
So this code would actually be more like:
char localhost[4];
localhost[0] = 127;
localhost[1] = 0;
localhost[2] = 0;
localhost[3] = 1;
snmp_set_var_typed_value( var, ASN_OCTET_STR,
localhost, 4);
IPv6 addresses would be handled in a similar way.

Not really - this questioner *was* using a fixed
length binary string, and was asking about the
difference between ASN_OCTET_STR and ASN_IPADDRESS
The two types work in basically the same way - they
both use *binary* string values, not printable ones.
