You have an endianness issue. From the Javadoc:

Note: Java's data structures are in big endian format. Roaring serializes to a little endian format, so the bytes are flipped by the library during serialization to ensure that what is stored is in little endian---despite Java's big endianness. You can defeat this process by reflipping the bytes again in a custom DataOutput which could lead to serialized Roaring objects with an incorrect byte order.

You first need to convert your IP to a 32bit integer as the error suggests. IPv4 consists of 4 blocks, each block is 8 bits, so it is 32 bits in summary.

You can write your own converting function, I believe this shouldn't be too hard but if it's problematic for you then there should be some npm packages you can use. For example, I found this one
