Bing IP address for proxy

[BigRob]

We are using on premise report server (not online).  Does anyone know of an IP address or range of address's which can be put into a proxy for allowing a connection to BING maps.

our proxy is old and only takes exceptions based on IP address  ( not name) and we cannot upgrade for the next 12 months due to operational reasons.

Thanks.

Hi @BigRob,

Not sure about this, maybe @mgmeyer know this?
