Prestacycle markets a home nitrogen system.  Have never used this product.  Bit too pricey for me. Personally a floor pump is a better value.  Different road conditions means different tire pressures for optimal ride. 

Is there a way to fill your tires with nitrogen?
Consider a machine having 4 eth ports running on it. Then to which eth port's ipaddress will the hostname resolve to?

Kindly guide me to some documentation to support your answers so that I could use them as proof in my project.

Thanks
