Spare time, in the home built a server, because the use of the cell broadband, IP bit dynamic allocation. Domain name resolution is a problem, my domain name is generally parked under the dnspod. Dnspod has the API to provide the modification, the use of Python simple implementation of the dynamic analysis. This way, you don't have to install a peanut shell. Nonsense don't say, look at the code:
