Technologies are described herein for migrating network addresses between host computers in a hybrid network environment. Before migrating a network address between a source host computer in a first network and a target host computer in a second network, potentially affected host computers in the networks are notified of the upcoming migration. This may cause an address translation module of an affected host computer to enter a fast polling mode. The networking infrastructures of the first and second networks are then reconfigured to effect transfer of the network address. This may include updating overlay IP mappings for the network address being migrated to point to the target host computer. Finally, the affected host computers are notified that migration of the network address is complete, causing the address translation module of the affected host computer to stop fast polling and return to normal operation with update mappings.
