IP addresses can be categorized as private and public addresses. Private IP addresses cannot be reached via the Internet, whereas public IP addresses can. For instance, most home networks have a router. This router will have a public IP address that is accessible through the Internet. Private IP addresses are not routable over the internet. So a computer A with a private IP address of 192.168.188.36 won't be able to locate a computer B having a private IP address of 10.8.0.26. They'll need to use public or WAN (wide area network) IPs. How to find out your IP Address. This portal is about your public and private IP addresses and all related security information. Whether you want to hide your IP, surf anonymously or ask yourself: what is an IP Address, anyway? We will give you answers and links to the best internet-related tools on the web.

IP addresses can be categorized as private and public addresses. Private IP addresses cannot be reached via the Internet, whereas public IP addresses can. For instance, most home networks have a router. Check my ip mac. This router will have a public IP address that is accessible through the Internet. If the Linux system is connected directly to the internet, the public and private IP addresses will be the same. However, in most cases they differ. Here is an example using the curl command.

The best thing about macs is that things work simply, nicely and silently. You do not really need to know much about macOS, computer architectures, file systems, application interfaces or protocols. You just use your applications and be creative. This applies to Merlin Project, Merlin Project Express and Merlin Server as well.

You can let Merlin Project for example publish project structures to the Calendar and have them synced among various devices. You see it accessing Contacts for the resources. You can get it to mail reports to project stakeholders, share your project to a Merlin Server, and sync edits of other users into one file seamlessly. It all simply works like a charm!

Occasionally though, a bit of technical understanding comes handy to you.

When you have for example a Merlin Server on a mac in your LAN (local network area) and need to access it from a portable device (macOS or iOS) over the internet. In such a case you need to know by which WANIP address to call it.

What is an IP address?

Computers within a computer network, need a label identifying themselfs uniquely. The label helps computer A to find computer B and ask for data or send any.
In internet communications this label is called Internet Protocol Address (IP Address in short).
There are various versions of IP addresses. The most commonly used is Internet Protocol version 4 (IPv4), while the deployment of the newer version IPv6 - dealing with the long-anticipated problem of IPv4 address exhaustion - is continuously increasing.

IPv4 addresses are defined as a 32-bit number and when displayed in notations look like: 12.345.67.90
IPv6 addresses use 128 bits and when displayed look like: fe80::c01:8348:bd92:cb6

You'll find more information in Wikipedia.

Where to find your IP address?

  • On a mac, open the 'System Preferences…'
  • Click on 'Network'
  • Select the top most listed interface on the left of the dialogue stating you are connected. If you are connected over the Wi-Fi, it will be 'Wi-Fi'. If you are connected over cable, it will read as 'Ethernet'.
  • See your IP address shown on the right side of the dialogue.

This IP address is your private IP address. It starts with 192, 10, or 172.

A private IP address only works within the LAN

Private IP addresses are not routable over the internet. So a computer A with a private IP address of 192.168.188.36 won't be able to locate a computer B having a private IP address of 10.8.0.26. They'll need to use public or WAN (wide area network) IPs.

What is a public or WAN IP?

That's easy. A public or WAN (wide area network) IP is an address which can be routed over the internet. In IPv4, it will start by any number other than 192, 10, 172, 1 or 255.

Public Vs Private Ip Address

This, or any other website that you access via your web browser, or even your mail server, have a public IP that you don't really see when you call it, because you prefer to call hostnames for reasons of clarity.

Even your router - the device connecting your LAN to the internet - has a WAN IP adress.

You can see your WAN IP in your router, or use web services.

Routers connect to the internet while protecting your LAN

Private

Public Private Ip Address Range

Routers are designed to block unwanted incoming connections. They offer - over DHCP - LAN IP addresses to your local devices. You can however choose to open independent ports and allow forwarding from/to specific private adresses if required.

Which is my WAN IP?

Access documents of Merlin Server from a portable device (macOS or iOS) over the internet

Now that you know by which WAN IP you can access the Merlin Server services, configure your access as explained in the related quick guide.

NOTE: For the connection to work, the admin of that remote LAN needs to enable port forwarding for the Merlin Server services (which are to be available over the WAN).
