Synology NAS Default IP Address

My work recently purchased a Synology DS3617xs NAS. How do I find the default IP of the NAS so I can do the initial setup?

From the documentation it seems you need either an internet connection or DHCP for automatic IP assignment (where you can then find the IP from your router).

Any help is greatly appreciated.

Synology Assistant does the job pretty well and is available for Windows, Linux and Mac, tested on Ubuntu 24.04 : https://www.synology.com/en-global/support/download/DS120j?version=7.2#utilities

It works offline, it needs to be downloaded before when being offline of course.

If nmap is installed and the Synology got no IP, one can directly connect a network cable, give it an IP and search with :

nmap -sn 169.254.0.0/16

In my case it turned out to be a strange acting switch so I never found the device until I replugged it and saw all ports had a 169.x.x.x address when using the assistant and direct cable.

Try connect directly server NIC <-> NAS NIC and wait for both devices to self-assign an IP address in 169.254.0.0/16.

Then:

ping synologynas.local

Result:

PING synologynas.local (169.254.254.112): 56 data bytes
Request timeout for icmp_seq 0
64 bytes from 169.254.254.112: icmp_seq=1 ttl=64 time=0.812 ms
64 bytes from 169.254.254.112: icmp_seq=2 ttl=64 time=0.958 ms

The IP address is revealed.

Alternatively visit http://synologynas.local in a web browser.

This worked for me using a Mac, running SynologyAssistant that could not find the NAS.

An update for those coming in from the future :)

All you need is actually just a device connected to the same network as the Synology NAS, so long as it has a browser with JavaScript — aye, any smartphone will do.

If you have no connection to the Internet (which was the case of the OP), put the following URL on the browser:

synologynas:5000
(synologynas.local:5000 on an Apple device)

If you do have Internet connection, but you're forced to go through an (internal) Web proxy server, then the command above might not work, in which case you should simply go to the following URL:

https://finds.synology.com/

It should just take a few seconds to find your NAS (on my network, it takes around 4-5 seconds) and give you its IP address, with a button at the end saying "Connect", something like this (my IP address is redacted for privacy reasons):

Find Your Synology NAS

There is no need to install anything on your system, no matter what hardware or operating system it runs on, although the device should at least have a graphics display, a JS-capable browser, and a means to type an URL in it — those are the only three requirements. You might even be able to use a smartwatch or SmartTV. A smartphone will most certainly work!

As you dont have DCHP option, please check the subnet and IP Range of the Switches. Then set the IP for the synology diskstation manually (search with the App Synology Assistant Windows download Link). Run synology assist from your computer makes sure the NAS is up and running all lights on and the blue light solid. LAN and disk lights should be flashing. It does take a few minutes for the unit to become available the first time. if you see the IP you can just type in the IP and get to you NAS as well without the synology assistant. You will need just the DSM file for your version/ unit. usually xxx.PAT. its that easy . Maybe the extra switch is the problem.

Pat file of your Diskstation: Link

As others said, it will spend time looking for a DHCP server to allocate an IP, and if it can't it'll eventually(*) default back to a self assigned IP in the 169.254.x.x range.

It takes quite a while to time out, so if you want to set it up without a DHCP server, you need to power it up and wait for 10+ minutes till it times out looking for DHCP responses.

IF you want to set it up without DHCP, you'll want to ensure your computers IP is setup to be able to talk to this range. (eg set your netmask to 0.0.0.0 so all traffic is sent directly, instead of any configured gateway)

I figured out a work-around.

I connected the NAS directly to my workstation using another LAN port I have installed on my workstation. I set the IPv4 connection for this port as Link-Local Only. When the LAN port identified its IP address, I used nmap to search the network to find other IP addresses. Since the only other item on this connection was the Synology, I was able to figure out the IP.
