Private IP address is assigned from the router to down the line connected devices like your Mac, smartphones, tablets, etc. Note that you will see the VPN/proxy server’s IP if you are using such connection. For example, go to our online IP finder tool to get your current public IP address. In this situation, the router will get a dynamic public address from your ISP which can be found by using any online tools. Since latest Mac models do not offer ethernet port, the only option for you is to use router/modem and connect wirelessly. Private and Public IP Addressīefore proceeding, it is necessary to understand the difference between the private and public IP addresses. In this article, we will explain various methods to find and change IP address in your Mac. Sometimes, you may also want to renew or change the IP address to a static one. All what you need are the IP, username and password for establishing a connection over same network. For example, you can type your Mac’s IP address like “//IP Address” in Windows File Explorer to access Mac’s file. You need to know this IP address in many situations like remotely connecting from other device, while using file sharing services, etc. So I presume that the ARP table of each switch will have the MAC and IP address associated with each port - especially if I run the 'address tracker' just before I do my 'trawl'.Internet protocol or IP address is a unique number assigned to every computer on the network for identification purposes. I already have a tool (SolarWinds IP address tracker) that pings each address in each subnet on a regular basis so enabling me (for example) to spot unused addresses. I have the IP address and SNMP community strings for each switch. Trawling is done using a 'home-coded' SNMP-based application so I can amend this as required. The laptops will go from site to site and so from switch to switch. The desktop PCs will use DHCP but will be (in effect) static. The printers and servers will mostly have static IP addresses. There will be a mix of printers, laptop and desktop PCs - with a small number of servers. I am looking to trawl the network looking to see what equipments are connected to which port of each switch. I have dozens of switches of various ages split across a number of geographically separate locations - each location joined by a third-party WAN provider so that I don't have access to the routers.

I'm late into this thread - but it looks as though this will help me.
