While i will answer this question, posting random packet captures for explanation to any mailing list is not appropriate. you shouldnt even bother using packet captures if you haven't any basic idea of how to interpret the results or how ip networking functions. you should take an intro to networking class, watch a youtube video or two, and read the fucking manual, before considering asking another human being to explain things to you. if you really dont care to do the work of learning yourself, you should pay someone else for their time. any answer you are given about this subject is going to be insufficient for you, as you dont have the knowledge or experience necessary to make the answer useful. Further, what you are doing is looking for explanations for a problem you dont have, and grasping for attention, not clarity. using all the tools that come with gnu/linux incorrectly will produce all kinds of confusing output, it is not another persons role to explain it to you. unless you are paying them.
now that i have wacked your hand with a ruler, i'll offer you the bitter sugar you asked for, however unsatisfying it may be.
this is loopback traffic. your computer is attempting to resolve a network time server (among other things). it is failing to do so. this is expected behavior, and by design.
