    Yes, there are quite a few ways:

    • Use a public (typically HTTP- or DNS-based) service to store IP addresses. It can be replicated using Fast-flux DNS and/or IP anycast.
    • Preconfigure some addresses, either in the binary or a configuration file. Create a list of peers with the highest uptime, and release that with the next version of your software.
    • Store reliable peers on the disk to try them the next time your program is started.
    • Use IP multicast to find other peers in your local network.
    • Randomly scan IPs. It may take a long time to find a remote peer, but it’s the only fully decentralized solution that works in the Internet. This method is only feasible for IPv4.
