To get your gateway's IP address, use the route
command with the -n
flag to translate hostnames into IP addresses (or rather, disable DNS lookups on the IP address).
$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 10.10.10.1 0.0.0.0 UG 100 0 0 eth0
The default gateway is the one where the destination is 0.0.0.0
, in this case, 10.10.10.1
.
Though I'm wondering, why are you manually assigning a static IP? Does your access device (router, wifi, whatever) not allow DHCP reservations? Most devices do these days. You just need to provide the MAC address, and many will already know the MAC by hostname. If your's doesn't you can get the MAC from ip
, the "link/ether" address:
$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
link/ether 00:50:56:10.10:21 brd ff:ff:ff:ff:ff:ff

or ifconfig
, the "HWaddr" address:
$ ifconfig
