1.8.2 For Advanced Users – hostname.local
If not using ZERO or your local network does not hand out a DHCP address the NR4400 will use an
IPv4 Link Local Address (169.254.0.0/16).
Once the NR4400 has either acquired a DHCP lease, or selected an IPv4 Link Local address, it will
advertise its hostname using Multicast DNS (mDNS). This means that it will be accessible on the local
network via
hostname.local
, where:
“hostname” is the devices model (eg. NR4416) followed by a dash “-“ and then its serial
number.
Gearlinx devices also support IPv6. If DHCPv6 or SLAAC is operational on the network, then the
device will acquire and IPv6 address via either protocol, and advertise that via mDNS, or it will
advertise its link local IPv6 address.
You can then configure your NR4400 series product a few different ways: via the local web UI, via a
secure shell connection or via the console port, all of which are described separately below.
1.8.3 Local Web UI
You can use an internet browser that is connected to the NR4400 network by typing in:
as detailed in the section above.
or if you know the “IP” address (for illustration only, in this example: 192.168.1.84):
Open a web browser and type:
The default username is "admin". The default password is printed on the NR4400 label on the base
of the unit as shown in Section 1.7 above. Username and password are case sensitive.
EXAMPLE 1: (IP not known)
Product: NR4416
Serial Number: 0110923000066
https://NR4416-0110923000066.local
EXAMPLE 2: (IP known: in this example 192.168.1.84)
For example:
An NR4416 with a Serial number of 0110923000066 would be found via:
nr4416-0110923000066.local
