If I remember correctly 239.255.255.250 is the multicast adress in ipv4, so perhaps you are sending IGMP packets so several hosts on the network? Though I am not completely sure so you might want to wait for someone more experienced with networks to reply.
Thanks a lot for the replies. Its good to hear that most likely its nothing to worry about. I’ll just keep it running like that then. Thank you for taking the time to reply, its greatly appreciated.
