Is it possible for different people to have the same public IP address?

Is it possible for different people to have the same public IP address?

As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. If they are connected via the same router, then they can have (share) the same public IP address yet have different private (local) IP addresses.

How are internal and external IP addresses assigned?

Public address ranges are assigned to ISPs by Internet Assigned Numbers Authority (IANA. On Home office networks that use a NAT router the internal IP addresses use a special IP address range. NAT allows thousands of computers on an internal network access the Internet using a single external IP address.

How to tell if I have two IP addresses?

As we’ve seen above, there are two ways to see the two different IP addresses: 1 Using an online service (or page like my What’s My IP Address? article) will tell you the internet IP address of your… 2 Using the “ipconfig” command in a Windows Command Prompt will tell you the local IP address of that computer.

Is the same computer name listed with two different IPs?

We have a Win 2008 R2 DC in a predominately Windows 7 production environment and I’ve noticed several instances of identical computer hostnames with 2 different ip addresses. From what I understand, you cannot join a new computer to a domain by using an existing hostname, so why the different ip addresses? What’s the best practice to resolve this?

Is it possible for two IP addresses to be duplicated?

The above 2 examples are where public IP addresses can be duplicated, one for evil and one for good. In neither case the two hosts with the same IP will be able to communicate with each other, but that is fine for the intended use cases.

Why are two computers on the same WiFi network the same?

The Answer. Ultimately, the computers seeing your traffic see the external IP address from your modem and not your physical computers internal IP address. More data is sent containing MAC addresses and things like that, but essentially one public IP address can represent an entire network of devices behind it.

How to create multiple IP adresses on Raspberry Pi?

What I already did was configuring /etc/interfaces/ and /etc/dhcpd.conf . But ifconfig still shows only one IP Adress.

Is the source IP address always the same in traffic manager?

No, Traffic Manager cannot guarantee that the geographic region we infer from the source IP address of a DNS query will always correspond to the user’s location due to the following reasons: First, as described in the previous FAQ, the source IP address we see is that of a DNS resolver doing the lookup on behalf of the user.

Can a virtual IP be used as a destination address?

In terms of actually using the Virtual IP address, they would be using in the security policies in the same places that other addresses would be used, usually as a Destination Address. UUID is now supported in for virtual IPs and virtual IP groups. This includes virtual IPs for IPv4, IPv6, NAT46, and NAT64.

How does the IP address of a router change?

Your router is connected directly to the Internet, and it’s assigned your public IP address (which may change over time). Your router is then responsible for sharing your public IP address among the other computers and connected devices in your home. Your router assigns local IP addresses to your connected devices.

Can a WiFi router have the same IP address?

Your Wifi router translates between the internal and external addresses. This allows you to have multiple devices inside your Wifi network, and your ISP only has to provide one IP address for your whole house. So, yes, someone else can have your same IP address.

How can I tell if my computer has two IPS?

If you have multiple network cards and you mannually configure the metrics (as windows usually does automatically), do an ipconfig and you’ll see that both network cards received an IP from the DHCP server (if they are configured for DHCP, otherwise they’ll use the statically assigned IP).
