Using DHCP reservations offers you a sort of poor-man's IP address management solution. You can see and change IP addresses from a single console and makes it so you can see what addresses are available without having to resort to an Excel spreadsheet (or worse, a ping and pray system). That being said, many applications require a static IP. If the server ...

Let me guess, both your systems are behind a router, right? If so, then there's NOTHING wrong with your IP address(es). Each computer on your private LAN does have its own IP address, but you only have one public Internet IP address, and that's what that site is showing you. Your router handles the back and forth address translation so that your two ...

The only web sites that can access MAC addresses, are sites that have you download a software component to interface with them, which allow the site to circumvent the usual rules. So you technically have to give permission first by doing that. ActiveX & WMI (Windows Interface via Windows Management Instrumentation) for Internet Explorer and Java are ...

If you set your IP address to 192.168.0.2 subnet mask 255.255.0.0, when your PC tries to communicate with the router, it won't matter that the router address is 192.168.0.255 because from your PC's perspective, the broadcast address is 192.168.255.255. So packets going to the router should be fine. The router will respond to 192.168.0.2 which it thinks is ...

The relationship between a fqdn (a web address) and an IP address can be many to many. In that many different IP addresses can serve the same websites, and a single IP address can serve many different websites. When a webserver at an IP address is hosting multiple websites, it uses headers in the request sent from your browser to know which site to send ...

Your router/gateway will be doing Network Address Translation [NAT] so that any outside IP reporter will only ever see the allocated address of your router. If you want to know your internal IP Address, then [for Win 7, but similar in others] go to Control Panel > Network & Internet > Network Connections. Right click the connection you see in there, ...

The IP address you see from that site is your public ip. It's the ip of your router not of your computer. Your router controls traffic between all the computers on your network and the outside world. Within your local network, your computers will have unique ones. From a terminal type ifconfig (or ipconfig from Windows) to see your local ip.

A mac address is just the unique number of your WIFI card in your phone. It contains no information about you. They can, at most, figure out what manufacturer made the device and the date it was made. That being said, once you are connected to their wifi, then they can see where you browse to and whatnot. This is the similar to if you connected to ...

Segment B can't overlap Segment A. Segment A takes up 131.107.168.0-131.107.171.255, so the next starting address that is unallocated is 131.107.172.0

The others have already answered you main technical questions and my comment to some of them answer your doubts about MAC address. So I'll just concentrate on this: And lastly, Is there an extra way to be anonymized that I can do? For example, can my system clock or anything else give an information? Yes, there is one more thing that can trip you ...

Both wa.net and for.us resolve to the same IP, so the network can't tell for which DNS domain an IP packet (and TCP segment and UDP datagram) is intended. For example, HTTP disambiguates network traffic addressed to the same IP by examining the HTTP Host: header to see the intended domain of the request (that's how virtual web hosting works), but named has ...


2

for.us is the first VirtualHost making it the "default" VirtualHost, so any petition that has no Host header (or not matches any of the other VirtualHosts) will end up there. HTTP/1.0 does not require Host header to work so it goes for the default VH. EDIT: If it is a home setup, quickest solution for that case is moving the "public" Virtual Host to the ...

Websites can't see your MAC address at all, so you don't need to use a VPN.

For CentOS with a DHCP leased IP, you can use this script: $ cat /etc/dhcp/dhclient.d/issue.sh #!/bin/bash update_issue() { awk -v \ r="$(ip -o addr | awk '/inet [1-9]+/ { print $2 " " $4 }')" \ '{ gsub(/%INTERFACES%/,r) }1' \ /etc/issue.template > /etc/issue } issue_config() { update_issue } issue_restore() { ...

Check the permissions on the /etc/ssh_host_rsa_key and /etc/ssh_host_dsa_key files. They must be 0600. I had the same problem and nothing worked. But when I did a sudo /usr/sbin/sshd -d I got a bunch of error messages nagging about those 2 files (that their 0644 permission was “too open”). Everything was fixed by giving those 2 commands: sudo chmod 600 ...

The internal address is the one used by the Wifi adapter in the phone. Even if you aren't connected to a Wifi it'll be there as long as you have been since the phone was booted (it maybe there even if it isn't enabled, IDK haven't looked myself).

Many routers won't accept/forward packets sent outside coming back (i.e. those meant for their own public IP). I've had such issues in the past as well. Also, as far as I'm aware, you can't use the hosts file to redirect traffic from one IP to another. That's really just meant to define hostnames your PC won't ask the nameserver for to get their IP. Try a ...

Just based on an IP address it is not possible to check if they belong to the same device. If you were to be in the same network(subnet), you could compare the MAC addresses and see if they are consecutive, which would give you some guarantee. If the remote router has some sort of service running which allows it to be identified (SNMP/Webservice with unique ...

There are 2 main things to understand here: "Segments" must be isolated from each other. Even though /22 can support 1022 hosts (2^10-2), you can't put the 600 hosts of segment A and the 300 hosts of segment B into the same network. If you did segment A hosts could "see" segment B hosts and that's not desired, thus the reason for different segments to ...

There must be a way to factory reset the device (if there is no dedicated switch, it can usually be done by pressing a combination of buttons on power-up or shorting specific contacts on the circuit board), I suggest reading the manual (or finding it online) and seeing how to do a factory reset. As far as I am aware, there is no way to connect to the ...

You can use Little snitch that will give you a graphical Network Monitor where you can select the Messages app and see what are the servers' IP Addresses (IPv4 or IPv6) that Messages app is connected to. Note: You may also need to check imagent and apsd processes. Nettop will also give you this information, just remember to look for imagent and apsd ...

Please note I have a suggested basic solution at the end of this answer. HTTP uses TCP by default, and while UDP does support multiple programs binding to a single port, TCP usually does not. So port 80 would appear not be free for a given IP in this instance as there can most likely be only one program using port 80 (TCP) with that IP at a time on the ...

You should check your routing table using, for example, netstat -nr. I'm not sure how your VPN client would handle a clash/overlap between your local and remote network addresses, but this might be a possibility you should exclude

I believe what you mean is that your router has a range for DHCP of lets say 192.168.1.1 - 192.168.1.100. You would like to put your static devices such as your access point outside of that range like 192.168.1.150? If so yes, ANY devices on your home network like printers, desktops, apple tv, Roku, wireless TV, ect. I would put a static address. It will ...

First, find out the MAC address of your Pi, then assign a static IP address to it on your router's admin page (on TP-Link routers it's under the DHCP menu). Then use port forwarding to redirect port 80 to the IP you assigned to your Pi.
