Thank you for using IPDynamic!

If you encounter any issues, please report them on GitHub.

Java Update

IPDynamic is compatible with Java versions 16 through 22. There is no support for lower versions java 8 or 11, but if you need a lower edition, feel free to contact me on Discord as SrCodex.​

Discord Webhook Delete the config.yml or add the option WebhookURL: "" below time-zone.

In the config.yml, you can set up a URL that will notify you when an IP is added to the blacklist (Only op1). Additionally, if a player with a blacklisted IP tries to join the server, the following information will be sent to the appropriate channel:

Username:

IP:

Alts:

Reason for blacklist:

Notification that they attempted to join the server.

For now, only one Discord webhook is supported to notify about attempts to connect with banned IPs, showing the account being used and any alts associated with that IP.

#          Dynamic IP Penalty Option 2
#         Read this before making changes
# To understand the new Ban OP2 system, you need to read this to get acquainted with what the new feature does. First and foremost, I have fixed an issue that was
# causing massive lag when applying a rank ban with option (OP2), as it was applying nearly 63,000 bans per second, resulting in significant lag.
# Therefore, I have divided the sanctions into 15 parts, with each part applying a ban to 4,392 accounts every 5 minutes. This will make the performance more stable.
# Once the IP range ban for option 2 starts, it will continue unless your server is turned off. So, how long should you wait? Option 2
# will apply a dynamic ban ranging from 0 to 255 on the last two digits, banning nearly 63,000 IPs, and this may take around 3-5 hours to complete.
#
# PERFORMANCE WARNING: The longer you set the ban time, for example, from 5 to 10 minutes, the higher the performance impact, but it will take longer for the ban system
# to apply restrictions to that dynamic IP. However, if you reduce the ban time from 5 minutes to 1 minute, it could cause very high lag and potentially crash the servers.
# If you still experience performance issues with a 5-minute ban, consider increasing the time to better suit your server’s needs.

ban-op2-minutes: 5 # Default 5 minutes

You need to delete the config.yml & Message-RU.yml file to obtain the new content.

Improvements:​

Now, when you request account data, it will display the date, time, and the real IP address used to register on the server for the first time. It will also show the last date of activity on the server.

Each disconnection will display the IP address used at the moment of disconnection, including the date and time.

Time Zone​

We have now added a time zone feature that can be modified in config.yml to set the time zone for capturing specific date and time data for an account when they log in for the first time.

Message-RU.yml​

A Russian player named Reizi updated the message in their native Russian language, so you now need to delete the current file to receive the new content.

IPDynamic Alts, help command visually updated

We have improved the display of the alt accounts and added a blacklisting system that will show up when requesting account data to check if a previous IP is on the blacklist. Additionally, we enhanced the symbols used in messages.

We also updated the help menu to make it more visually appealing
