A unique local address is similar to a private IPv4 address and cannot be globally routed. These addresses have the prefix fc00::/7 . If this address is similar to an IPv4 address, how can it be ensured that the systems in a local network also have different IP addresses belonging to that network? The network…
I think I'm making a mistake and would like to ask again. I've connected an old firewall to a switch for testing. The switch is connected to a client with an APIPA address of 169. The firewall has an IP of 192.168.1.1 (the default IP). Why can I access the firewall interface despite using a…
If I change the IP of the Fritz!Box to e.g. 192.168.199.1 Leave DHCP active And under DNS, I enter 192.168.199.1 as the primary DNS. Why doesn't the Fritzbox check that I want to access the interface via Fritz.box? Only the IP works. Does this really only work if it's the default? If so, I'm interested…
Hello :), I would like to assign a static IP address to my Raspberry Pi 5. I have a Huawei router that also offers this option, but when I create a rule that assigns an IP address to the Pi's MAC address, it doesn't work. The DHCP server's address range is set so that the…
Hello, for a few days now I've had a problem on two computers where they are not being assigned an IPv4 address correctly. It works like this: DHCP assigns the PC a temporary address starting with 169 -> in the router interface, the PC is assigned an address -> the PC duplicates this and releases…
I'm currently using the one on my Fritzbox 5590 fiber, but unfortunately, it can't do a lot of things. I'd like to use a different one, but I don't know of any good, up-to-date, standalone Docker servers. I already have a good DNS server with Adguardhome, but DHCP isn't really that great. It should support…
Since I have two LAN connections for the front door that end outside, I'm wondering whether it would be sensible to secure my network using a subnet mask of 255.255.0.0. The area of e.g. 172.18.1.1 to 172.18.1.254 is for new devices.. (i.e. all devices that I do not register in my DHCP server end up…
The router logs show which device or the IP of the device is accessing a different IP (website). Can you find out the exact website based on that information alone, or would that be impossible?
First, my wifi was gone on my PC and I had no way to reconnect and now it says no DHCP server found
Hi, I've been having problems with my W Speedport 724V from Telekom for a while now. The entire LAN network keeps failing after a while. I've checked and reset all switches and sockets, and it doesn't help. I looked at the settings, and the router assigns new IP addresses every three weeks. In fact, the…
Hello I bought a TP Link device and am trying to connect my PC to the LAN. It worked the first day. But the next day, I couldn't get internet access. It worked normally, but the LAN didn't. I don't know what to do. I've tried everything, even restarting the adapter… but I still can't…
Good morning. I wanted to change my Ethernet to 1 Gbit/s because I have a 400 Mbps connection. However, when I set the duplex to 1 Gbit/s, the diagnostics tell me that the DHCP server cannot be reached. At 100 Mbps, the connection works fine. I have an Asus RT-AX57 router and a CAT 7…
