I'm not sure if that is supposed to work. The NTS-KE client doesn't provide the IP address to the server (at least the

gnutls_server_name_set() function doesn't allow that), and gnutls as a TLS server probably doesn't check the address of the socket in expectation that there will be a matching address in one of the certificates. Maybe an RFE could be submitted for that.

Yes, you can specify multiple addresses in the certificate. Just add more lines with "ip_address = ...". No need to use separate certificates.

Specifying multiple ip_addresses is valid. I found that when I set ntsrefresh to 1, the TLS handshake fails every 24s after the TLS handshake fails. This seems to be regular. Where can I know this from the code?
