Strange IP address

I run HA Core 0.108.8 on Raspi Model 4 64bits and have given Raspi a static IP address from my router.
When checking with Terminal&SSH I found some IP:s that dont belong to my subnet (192.168.1.0/24).
They are 172.30.xx.xx … check below … where do they come from and should I be concerned?

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
16: eth0@if17: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:1e:21:00 brd ff:ff:ff:ff:ff:ff
    inet 172.30.33.0/23 brd 172.30.33.255 scope global eth0
    valid_lft forever preferred_lft forever
    
    
$ cat /etc/hosts
