    Bug 1473247 - Part 1: Fixing the issue that the IP addresses won't be set for first party domains. r=arthuredelstein,baku
    
    Right now, the firstPartyDomain won't be set when using IP addresses as
    first party domains. It is because of that the TLD service won't accept
    IP addresses as valid hosts. The patch fixes this problem by detecting
    that if the host is a IP address. If it is, we will still set the
    firstPartyDoamin with the IP address.
