Requirements:

• Java 8 or newer for 1.0.x
• Java 21 or newer for 1.1.x
• Java 25 or newer for 1.2.x

Basic usage:

• Gradle implementation 'io.github.hirsivaja:jipcs:1.0.0'
• Java module-info requires com.github.hirsivaja.jipcs;
• To decode an IPv4 or IPv6 packet with headers call IpPacket.fromBytes(byte[] ipPacket) -method
• To encode your IPv4 or IPv6 object call IpPacket.toBytes() -method
