Author:

Jeff Gehlbach <jeffg@opennms.org> This class exists solely to work around a bug in the Net-SNMP BER library that causes Net-SNMP agents prior to version 5.4.1 on 64-bit platforms to encode IPv4 addresses as 8 bytes rather than 4 bytes. SNMP4J correctly discards these representations by default. This class will be used in place of org.snmp4j.smi.IpAddress only if we call org.snmp4j.SNMP4JSettings.setExtensibilityEnabled(true) AND set the system property org.snmp4j.smisyntaxes to refer to a classpath properties resource (relative to class org.snmp4j.smi.AbstractVariable) that overrides the default mapping for BER type 64 (nominally IpAddress). See the file opennms-snmp4j-smisyntaxes.properties. The workaround for 8-bit long IP addresses will be enabled only if the system property org.opennms.netmgt.snmp.workarounds.allow64BitIpAddress is set to "true".
