Replacement Sky Stream - odd ip behaviour

[Dshepherd]

We recently had a replacement Sky Stream Puck. All good except my router is showing it as having 2 ip addresses. This device is only connected via wifi, no ethernet cable. One address is valid for my network the other address is ...

100.64.11.1 

Any thoughts here ?

Your router is not reserving an address for the previous sky puck ? Powering off your router for 30 mins or so (depending on your isp) might release / renew the ip addresses if it is

100.64.x.x/10 is a rather peculiar netblock used by ISPs for CGNAT: technically it isn't actually valid for either the internet or a LAN.

Personally I'd suspect that's just a weird glitch caused by something your ISP is doing.
