ifconfig shows the interface but no IP

Question

I'm troubleshooting some networking issues on our 2-interface centos machine. The machine has two interfaces, for 162.* and 172.* subnetworks. The machine used to work properly but as of today I can only access the machines within the 162.* subnetwork, none of 172.* I noticed that ipconfig displays the 172.* interface with "scopeid 0x20" instead of the ip address.

ifconfig -a

The second interface, eno33557248, instead of the IP shows "scopeid 0x20".

This interface exists under /etc/sysconfig/network-scripts/ifcfg-eno33557248. The file reads:

TYPE="Ethernet"
BOOTPROTO="none"
DEFROUTE=no
IPV4_FAILURE_FATAL=yes
IPV6INIT="no"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"
NAME=eno33557248
UUID="e157d343-3acb-4498-8ab2-83251bf5e098"
ONBOOT="yes"
HWADDR=00:50:56:BA:68:75
IPADDR=172.16.3.2
PREFIX=24
GATEWAY=172.16.3.1

This file has not changed for years and the machine used to work properly. I don't know why the 172.* interface displays "scopeid 0x20" instead of the IP or what it means but problems with the 172.* subnetwork make me believe there is something wrong about it. If so, how do I fix this interface?

Update1: Output of ip link:

Update3: output of ip route. Note 172.* is not in the list.
