networking – Why do I have three IPv6 address, but only one IPv4 for my machine on my LAN interface?

Is there a reason to have 3 IPv6 address just for one machine?

ifconfig:

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 2383  bytes 270436 (270.4 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 2383  bytes 270436 (270.4 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.1.38  netmask 255.255.255.0  broadcast 10.0.1.255
        inet6 2a00:1028:9190:17d2:1db0:a9ff:b6e4:90ca  prefixlen 64  scopeid 0x0<global>
        inet6 fe80::55dc:73b2:3cc:96  prefixlen 64  scopeid 0x20<link>
        inet6 2a00:1028:9190:17d2:af53:27e1:c22d:1225  prefixlen 64  scopeid 0x0<global>
        ether 5c:3a:45:55:ae:b5  txqueuelen 1000  (Ethernet)
        RX packets 62545  bytes 81808465 (81.8 MB)
        RX errors 0  dropped 238  overruns 0  frame 0
        TX packets 36014  bytes 5756972 (5.7 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Why do I have:

        inet6 2a00:1028:9190:17d2:1db0:a9ff:b6e4:90ca  prefixlen 64  scopeid 0x0<global>
        inet6 fe80::55dc:73b2:3cc:96  prefixlen 64  scopeid 0x20<link>
        inet6 2a00:1028:9190:17d2:af53:27e1:c22d:1225  prefixlen 64  scopeid 0x0<global>
