Abstract
Flexibility of handling of multicast information using an Internet Group Management Protocol (IGMP) is improved by overcoming failures to respond to group specific queries. Such failures occur when heterogenous host devices are used on a common network. When a failure to respond to a group specific query is experienced, a general query is used to obtain information that was not provided by the group specific query.
