How to test whether a secondary inet address exists on an eth interface?

RHEL9 Sometimes server 1 has the secondary address 10.143.170.80/24, and sometimes server 2 has that secondary address. My script needs to test which server has that secondary address. However, ip address show dev ${VirtDev} secondary always returns 0, whether or not the secondary address exists or not. Server 1: ip address show dev $VirtDev secondary echo $? 0 Server 2: ip address show dev $VirtDev secondary 2: ens33: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:50:56:8e:73:35 brd ff:ff:ff:ff:ff:ff altname enp2s1 inet 10.143.170.80/24 scope global secondary ens33:0 valid_lft forever preferred_lft forever echo $? 0 This works, but seems janky: Exists=$(ip address show dev $VirtDev secondary) [ -n "$Exists" ] && echo exists || echo not exists Is there a better way? EDIT: when parsing json... ip -j -4 a ls to 10.143.170.80 | jq -e .[].addr_info [ {}, { "family": "inet", "local": "10.143.170.80", "prefixlen": 24, "scope": "global", "secondary": true, "label": "ens33:0", "valid_life_time": 4294967295, "preferred_life_time": 4294967295 } ] ip -j -4 a ls to 10.143.170.80 | jq -e .[].addr_info.local jq: error (at :1): Cannot index array with string "local"
