Hello, thanks for your interest in the project!

The answer depends on your implementation. The DHCP Server itself does not track assignments since everything is managed by whatever Backend you assign to it.

If you are using the memory backend, you could see what assignments are active by reading from its index of assigned records: MemoryBackend.records

Implementation would vary widely based on what you are trying to do, since those assignments are obviously only made during runtime. You would likely need some sort of polling mechanism for regular reporting running alongside the server itself. You could achieve this via threading, but pyserve also offers an asyncio alternative to listen_udp_threaded which is called listen_udp_async which could be easier to use.

A simple implementation might look something like this:

import asyncio
import logging
from ipaddress import IPv4Address, IPv4Network

from pyserve import listen_udp_async

from pydhcp.v4.server import Server
from pydhcp.v4.server.backend import MemoryBackend, CacheBackend

# prepare simple memory backend as base provider
memory = MemoryBackend(
    network=IPv4Network('192.168.1.0/24'),
    gateway=IPv4Address('192.168.1.1'),
    dns=[IPv4Address('8.8.8.8'), IPv4Address('8.8.4.4')],
)

# wrap backend w/ cache (not really useful here but for non-memory answers)
backend = CacheBackend(memory)

# configure optional logger for server implementaion
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger('myserver')
logger.setLevel(logging.INFO)

async def report_assignments():
    while True:
        await asyncio.sleep(5)
        print('== Assignments ==')
        for mac, record in memory.records:
            print(f' - {mac} = {record}')

async def main():
    report = report_assignments()
    server = listen_udp_async(
        address=('0.0.0.0', 8080),
        factory=Server,
        allow_broadcast=True,
        backend=backend,
        logger=logger,
        server_id=IPv4Address('192.168.1.1') # dhcp server address
    )
    await asyncio.gather(report, server)

asyncio.run(main())

Hope that helps. Good luck and feel free to ask any questions you have :)
