weird occurence

Ok so ive asked something similar in the past, but this is slightly different. I just tried connecting to my wifi router, and a ‘‘new network detected’’ popup appeared. It had a 169.254.183 132/16 ip, which from what i recall means it’s public and couldnt be assigned by the dhp. I dont understand why this happened, as it is the same network ive always connected to. I restarted my computer, and was able to connect to my wifi Normal ip(192).
Is this something to be concerned over? was that a hacker?
How come the new connection popup onlygives options for work, home, school, why not an option to BLOCK the connection?
The official ip was weird…it said 169.254.183 and then said 132/16 is this normal?

It’s a fall over IP-address range that Microsoft Windows use whenever it can not get an IP-address from the DCHP server.

The /16 is the subnet mask, it says how many bits in the subnet mask that are set to 1 so in this case 16 which would look like 11111111.11111111.00000000.00000000 (binary) which in turn means the subnet mask in decimal is which in turn means that the address range for the IP-address you were assigned is - ( is not assignable and is the broadcast address)

Does that help?

thanks for the reply, what confuses me, and maybe i dont understand how the internet works, but when you guys/girls say that the 169s are assigned because an ip can’t be obtained, i thought my wifi already had an ip address since it is a set up network…i thought each time i signed onto that wifi network, the same ip was used whether it’s now r ten years from now, it’s all set up?

My main concern was that when i clicked on my wifi to sign in that somehow a hacker interjected and i logged onto his network(the 169) and not mine, but it sounds like the 169 address is harmless and not private lol.

I don’t really know about that. Basically you have an external/public IP address, lets just pretend it’s (it’s not but lets pretend) and then you have an internal/private network which is in the, or subnet, these addresses are then assigned to different devices in your LAN using DHCP (usually done by a router in home networks) When your computer can not be assigned an IP address from the DHCP server for whatever reason, Windows will assign the computer an IP address in the subnet, this is in order to maintain connection to other computers also configured to use such addresses, e.g most computers using Windows etc.

A computer can only lease an address from the DHCP for a certain period of time and once that time is out the computer will either have to renew the lease or be assigned a new IP, hence it’s common your computer will need a new private IP-address if it has been shut down for a while. … … Or something like that, honestly I didn’t spend much time learning about how DHCP works technically… :embarassed: You can read more about DHCP here: Dynamic Host Configuration Protocol - Wikipedia
