Does anyone know the specs for the X-GEO HTTP header? I am seeing some in my logs, and looked for a spec or something, but didn't find anything that explains the values I am seeing. Any reference to the header I find online show values like US etc. e.g.
Here is part of packet:
X-Geo: US X-Real-IP: 54.83.132.159

…But there is no explanation of that particular header.
The ones I see seem to be encoded but I am not sure of the format. Here is a sample of some of the values I am seeing. All of them follow this similar format:

Is there any info behind this type of value if decoded? Anyone know there the spec for the x-Geo header might live?
