Is it real arp spoofing attack or capturing error in wireshark?

edit

Well I was sharing internet to my linux laptop from android mobile through usb tethering.

during usage I decided to turn OFF ipv6 in the laptop network manager(network settings). As soon as I turned off the ipv6 and applied. 2 additional MAC addresses F1:F1:F1:F1:F1:F1 and F2:F2:F2:F2:F2:F2 appeared in the wireshark capture and "duplicate use of 192.XXX.XX.XX1 detected!". The new MAC addresses were not identifiable in wireshark MAC lookup list. I am giving the detail below:

MAC XX:XX:XX:XX:XX:XX

IP Add  192.XXX.XX.XXX

Default Route   192.XXX.XX.XX1

DNS     192.XXX.XX.XX1

|  S.no  |        IP      |       MAC     | ARP Packets | Grat ARP packets | ARP spoofing |
|---------------------------------------------------------------------------------------------|
|  1   |   192.XXX.XX.XX1  |  F1:F1:F1:F1:F1:F1  |     150     |    0        |      Yes     |
|---------------------------------------------------------------------------------------------|
|  2   |   192.XXX.XX.XX1  |  YY:YY:YY:YY:YY:YY  |     168     |    0        |      Yes     |
|---------------------------------------------------------------------------------------------|
|  3   |   192.XXX.XX.XX1  |  F2:F2:F2:F2:F2:F2  |      27     |     0        |      Yes     |
|---------------------------------------------------------------------------------------------|
|  4   |   192.XXX.XX.XXX  |  XX:XX:XX:XX:XX:XX  |     324     |   0        |      No      |

Also there is additional information "11080 UDP: Possible traceroute: hop #2, attempt #1"

11080 UDP: Standard query 0x7ff7 A exa*****.org OPT

and

14280 UDP: NTP Version 4, client

[Expert Info (Chat/Sequence): Possible traceroute: hop #5, attempt #1]

Additionally

tcp.flags.syn == 1 and tcp.flags.ack == 0          were 315(1.9%)

tcp.flags.syn == 1 and tcp.flags.ack == 1         were  219(1.3%)

so there is difference in both captures here I am referring this post
