GSteiner Posted December 3, 2020 Posted December 3, 2020 I have one ISY on a condo building network with DHCP. There have been occasions when I am unable to reach it via the portal (long story). I have the unit send me daily emails to check in. Would be really nice to have a variable with the local IP address so that I can include in the daily email which will allow me to log in locally without having to do an exhaustive search of network addresses. Does such exist? If not, this would be a simple but nice addition.
oberkc Posted December 3, 2020 Posted December 3, 2020 To clarify...do you have control of the wifi at the condo, or is it public? The reason that I ask is wondering if you have the opportunity to set a static IP address.
DennisC Posted December 3, 2020 Posted December 3, 2020 If you have access to the buildings system you should be able to make a DHCP reservation in settings. This would prevent your IP address from changing. If not, maybe set up a DNS with one of the companies that provide this service.
larryllix Posted December 3, 2020 Posted December 3, 2020 If you are using ISY Portal you will have full access to your ISY without knowing the LAN IP address of it anyway. If you have access to the router and are using port forwarding, some newer routers had a port forwarding that would follow the IP address of the destination device.
GSteiner Posted December 3, 2020 Author Posted December 3, 2020 Hello. Thanks for all of the suggestions. I am aware of all of the suggested options. And, like I said it is a long story which I don't want to get into here. The suggestions do not work for my situation. Do believe this answers my question. There is no variable with this information. Thanks.

GSteiner Posted December 4, 2020 Author Posted December 4, 2020 Michel provided this helpful information to quickly find an ISY on a network: If you are on windows, isy should resolve to your ISY … so, you can simply “ping isy” On all platforms “arp -a” gives you a list of devices on your network. Simply look for one with MAC address starting with 00:21:b9 1

If you are on the network, you can easily see quite a bit of traffic.

My thought was if you received an email with the ISY address in it and someone got the email, you just given them the information to your system. While it may not mean anything to the avg person, someone with knowledge could get enough information to potentially get inside. Same reason most people on her will cross out their up addresses when they post on here

So having a variable substitution method for the IP address is no less secure. It is the user's decision to publicize that content. 1

As a business, udi may not want to open themselves up to that by easily providing a method. 1

Allowing the user to get the current IP address of the ISY on a (typically) closed network is nothing compared to: - disarming a security system - unlocking a lock - running a furnace Plus, the IP address is included in every single network connection the ISY makes (at least on the local LAN). 1

That's up to udi whether they want to cross that push. It's not something I would do and bring that they haven't (nor commented)I would think there's a chance they feel the same way. What can be found while you're on your own network vs sending via an unsecured method are 2 different things Edited December 7, 2020 by lilyoyo1
LFMc Posted April 14, 2021 Posted April 14, 2021 @gzahar If you look in the Internet Header of the email you got from your ISY, it contains the ISY private and public IP address in it. Simple to find the IP that way. In Outlook, you click File/Properties to see it. Sat, 10 Apr 2021 09:15:16 -0700 (PDT) Received: from [xx.xx.xx.xx] ([xx.xx.xx.xx]) The first is the private IP and the second is the public. 2
