Abstract
A method and associated systems for identifying hardcoded network addresses. A network-migration tool requests from a network certain types of data that may identify IP addresses used by the network and receives a subset of the requested data. The system infers from the manner in which received data characterizes IP addresses which of those addresses are likely to be hardcoded. If the system receives a list of server affinities, it infers that an IP address used for communication between servers in a same affinity group is hardcoded if that address is not listed by an associated DNS server. If a received ARP cache lists an IP address as having been resolved to a MAC address, the system infers that the IP address cannot be hardcoded. If a received TCP trace log lists an address without a corresponding hostname the system infers that the address is hardcoded.
