[pkg-dhcp-devel] isc-dhcpC (client) open ports

[hdpcstuffd1+18 at elektromaniak.wz.cz]

Hi!

I noticed that my isc-dhcp-client is listening on 3 ports.
There is the regular ipv4 port 68/udp.
And two random ports - udp and udp6.

The network where I noticed this runs udhcpd as a dhcp4 server, no dhcp6 is
present.

What are those two ports used for?
If not for much, can I disable the feature in the client?
It could be requested by the server, but I doubt that - udhcpd is too simple
for that.
The machine sometimes roams to the open internet (public IPv4), open ports are
a big deal.

Thanks for any hints
