Remove secondary IP with NetworkManager / nmcli

I tried to assign a static IP to my Ubuntu 16.04 server using nmcli, which worked but it still has the original IP reserved as a "secondary" IP. I'm not sure how to get rid of it. 10.163.148.36 is the original IP of the server and 10.163.148.194 is the new IP I want it to switch to. I used the following nmcli command to set the IP address: nmcli connection modify 'Wired connection 1' ipv4.addresses '10.163.148.194/24' ipv4.gateway '10.163.148.2' ipv4.method 'manual' ipv4.ignore-auto-dns 'yes' connection.autoconnect 'yes' ipv4.dns '10.10.10.10 10.20.10.10' Note the two IP addresses for the ens160 interface. aruba@ubuntu:~$ ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens160: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:50:56:8a:10:64 brd ff:ff:ff:ff:ff:ff inet 10.163.148.194/24 brd 10.163.148.255 scope global ens160 valid_lft forever preferred_lft forever inet 10.163.148.36/24 brd 10.163.148.255 scope global secondary ens160 valid_lft forever preferred_lft forever inet6 2006::b0a3:b9ab:2f96:a461/64 scope global temporary dynamic valid_lft 604254sec preferred_lft 85254sec inet6 2006::dc94:ead6:e8ef:8095/64 scope global mngtmpaddr noprefixroute dynamic valid_lft 2591987sec preferred_lft 604787sec inet6 fe80::941e:5fa3:3571:df76/64 scope link valid_lft forever preferred_lft forever My nmcli connection details: aruba@ubuntu:~$ nmcli connection show "Wired connection 1" connection.id: Wired connection 1 connection.uuid: d724141e-4c7f-3fc9-97b1-c37e014aebe4 connection.interface-name: -- connection.type: 802-3-ethernet connection.autoconnect: yes connection.autoconnect-priority: -999 connection.timestamp: 1481582261 connection.read-only: no connection.permissions: connection.zone: -- connection.master: -- connection.slave-type: -- connection.autoconnect-slaves: -1 (default) connection.secondaries: connection.gateway-ping-timeout: 0 connection.metered: unknown connection.lldp: -1 (default) 802-3-ethernet.port: -- 802-3-ethernet.speed: 0 802-3-ethernet.duplex: -- 802-3-ethernet.auto-negotiate: yes 802-3-ethernet.mac-address: 00:50:56:8A:10:64 802-3-ethernet.cloned-mac-address: -- 802-3-ethernet.mac-address-blacklist: 802-3-ethernet.mtu: auto 802-3-ethernet.s390-subchannels: 802-3-ethernet.s390-nettype: -- 802-3-ethernet.s390-options: 802-3-ethernet.wake-on-lan: 1 (default) 802-3-ethernet.wake-on-lan-password: -- ipv4.method: manual ipv4.dns: 10.1.10.10,10.2.10.10 ipv4.dns-search: ipv4.dns-options: (default) ipv4.addresses: 10.163.148.194/24 ipv4.gateway: 10.163.148.1 ipv4.routes: ipv4.route-metric: -1 ipv4.ignore-auto-routes: no ipv4.ignore-auto-dns: no ipv4.dhcp-client-id: -- ipv4.dhcp-timeout: 0 ipv4.dhcp-send-hostname: yes ipv4.dhcp-hostname: -- ipv4.dhcp-fqdn: -- ipv4.never-default: no ipv4.may-fail: yes ipv4.dad-timeout: -1 (default) ipv6.method: auto ipv6.dns: ipv6.dns-search: ipv6.dns-options: (default) ipv6.addresses: ipv6.gateway: -- ipv6.routes: ipv6.route-metric: -1 ipv6.ignore-auto-routes: no ipv6.ignore-auto-dns: no ipv6.never-default: no ipv6.may-fail: yes ipv6.ip6-privacy: -1 (unknown) ipv6.addr-gen-mode: stable-privacy ipv6.dhcp-send-hostname: yes ipv6.dhcp-hostname: -- GENERAL.NAME: Wired connection 1 GENERAL.UUID: d724141e-4c7f-3fc9-97b1-c37e014aebe4 GENERAL.DEVICES: ens160 GENERAL.STATE: activated GENERAL.DEFAULT: yes GENERAL.DEFAULT6: yes GENERAL.VPN: no GENERAL.ZONE: -- GENERAL.DBUS-PATH: /org/freedesktop/NetworkManager/ActiveConnection/0 GENERAL.CON-PATH: /org/freedesktop/NetworkManager/Settings/0 GENERAL.SPEC-OBJECT: / GENERAL.MASTER-PATH: -- IP4.ADDRESS: 10.163.148.194/24 IP4.ADDRESS: 10.163.148.36/24 IP4.GATEWAY: 10.163.148.2 IP4.DNS: 10.10.10.10 IP4.DNS: 10.20.10.10 IP6.ADDRESS: 2006::b0a3:b9ab:2f96:a461/64 IP6.ADDRESS: 2006::dc94:ead6:e8ef:8095/64 IP6.ADDRESS: fe80::941e:5fa3:3571:df76/64 IP6.GATEWAY: fe80::213:1aff:fec7:f857 Lastly, my NetworkManager config: aruba@ubuntu:~$ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=keyfile,ofono dns=dnsmasq [ifupdown] managed=true
