I forgot to attach this file (findings.txt) with the details (lsof output,
strace output, etc.).

Using 'lsof' I can see that the UDP sockets still has the old
local addresses (even more than one of them: xx.y.88.88, xx.y.81.94,
xx.y.137.222; while the machine has the IP addresses aaa.bb.54.99 and
vv.zzz.155.129 currently):

And none of the above addresses are configured currently:
