Network address book
The address book contains the node ID and node address information to sync with Hedera node(s) in a specific network. The address book file IDs for each network are 0.0.101 and 0.0.102. You can obtain the address book information by requesting the contents of the file 0.0.101 or 0.0.102 (FileContentsQuery()). The network information can also be found in your Hedera portal account.
