Why is my netstat -an command report ESTABLISHED connection between interfaces that do not belong to my machine? NOTE: one end-point is Apple server with IP address: 17.171.43.55

Configured interfaces on my machine are listed below:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384

options=3<RXCSUM,TXCSUM>

inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1

inet 127.0.0.1 netmask 0xff000000

inet6 ::1 prefixlen 128

gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280

stf0: flags=0<> mtu 1280

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>

ether c8:bc:c8:a2:71:90

media: autoselect (none)

status: inactive

en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

ether c8:bc:c8:e1:b5:90

inet6 fe80::cabc:c8ff:fee1:b590%en1 prefixlen 64 scopeid 0x5

inet 192.168.204.44 netmask 0xffffff00 broadcast 192.168.204.255

media: autoselect

status: active

p2p0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 2304

ether 0a:bc:c8:e1:b5:90

media: autoselect

status: inactive

fw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 4078

lladdr dc:2b:61:ff:fe:d4:d3:82

media: autoselect <full-duplex>

status: inactive

As you can see, the only IP address currently configured is: 192.168.204.44

Could you please explain why does netstat -an report back connections with endpoints that are clearly not on my machine?!?

Any idea what is going on here?
