--- Comment #2 from François Gouget  ---
I have run the test with extra traces on cw-rx460/Windows 10 1507 and it does
not have this local link entry:

Windows 10 1507:

Windows 10 21H1:
nsi.c:667: AF_INET: 0 InterfaceIndex=1 state=6/6 s_addr=224.0.0.22

nsi.c:667: AF_INET: 4 InterfaceIndex=10 state=6/6 s_addr=10.42.42.255

nsi.c:667: AF_INET: 5 InterfaceIndex=10 state=0/0 s_addr=169.254.169.254

nsi.c:667: AF_INET: 6 InterfaceIndex=10 state=6/6 s_addr=224.0.0.22
nsi.c:667: AF_INET: 7 InterfaceIndex=10 state=6/6 s_addr=224.0.0.251
nsi.c:667: AF_INET: 8 InterfaceIndex=10 state=6/6 s_addr=224.0.0.252
nsi.c:667: AF_INET: 9 InterfaceIndex=10 state=6/6 s_addr=239.255.255.250

The only references I have found concerning 169.254.169.254 mention its use on
Amazon EC2. So I don't know why it would appear on this machine.
