A MAC address and your IP address are both key components to networking, but they serve different purposes, and are visible in very different ways.
When your computer can’t get an IP address any other way, it assigns itself a 169.254 IP address. It’s a sure sign of a problem.
While you cannot find the specific owner of an IP address, I’ll look at a few tools to see what IP-related information you can get.
With one exception, having an open port is not dangerous. But the way that ports work is interesting!
Some smart routers can act as a local DNS servers in an attempt to speed things up.
Finding out that you are on a blacklist can be a nightmare. So how do you get off of it?
It’s important to understand the terminology when it comes to masking an IP address. Depending on your security needs, some need to be done differently.
In this scenario, you’ll end up with two IP addresses, but the hub and router won’t each get one. I’ll explain.
While getting someone’s name and address from their IP address is technically possible, it’s also typically difficult and requires involving law enforcement.
It can be surprisingly hard to tell if an email account has been hacked, especially when the hackers are covering their tracks. I’ll show you a few possible signs.
Comparing your machine’s IP address to that reported by a website may result in a surprising difference. I’ll explain why that is and why it’s a good thing.
It’s typically impossible for the average computer user to determine who’s reading your email, particularly since tracing through a an IP address is virtually impossible with legal assistance. The best option is securing your account from any prying eyes from the start.
It’s not going to be easy. Only law enforcement has the ability to get full IP address information. The curious thing is, how do you have access to the email?
People can tell very little from your IP address. For example, they cannot tell who or where you are. How much they can tell varies a great deal.
We’ll look at some of the specific information that you’re making available to every website you visit, and briefly explain each.
“Limited Connectivity” displays when your computer is having problems completing its network configuration. It might as well mean “no connectivity”.
Once you’ve been assigned a static IP address you’ll need to configure the network-connected device manually to use it. We’ll look at how.
If there is a conflict with your IP address, it could result in only one of the machines on your network working at a time.
