net.i2p.data.i2np.I2NPMessage

Packages that use I2NPMessage
net.i2p.data.i2np: The Invisible Internet Network Protocol (I2NP) is only a part of how an application can send messages over the network.
net.i2p.router: The I2P router application handles the I2P network communication.
net.i2p.router.message
net.i2p.router.networkdb
net.i2p.router.networkdb.kademlia
net.i2p.router.transport: The transport system allows the usage of communication layers that are below I2P in the stack, on which I2P messages are sent.
net.i2p.router.transport.udp: The UDP transport (also known as 'SSU transport') allows passing I2P messages on top of UDP.
net.i2p.router.tunnel
