    You audit on two fronts, look at the systems for the controling
    application<s> required to use it and you look for connections to their
    server<s>:
    
    Non-authoritative answer:
    Name:    www.gotomypc.com
    Address:  63.251.224.169
    
    
    Non-authoritative answer:
    Name:    gotomypc.com
    Address:  63.251.224.169
    
    And if one wants to be a tad more careful in what they block perhaps a
    whole class C:
    
    [jengate.thur.de]
    Process query: '63.251.224.169'
    Query recognized as IP.
    Querying whois.arin.net:43 with whois.
    
    InterNAP Network Services (NETBLK-NETBLK-PNAP-11-99) NETBLK-PNAP-11-99
                                                       63.251.0.0 -
    63.251.255.255
    Expertcity.com (NETBLK-PNAP-SFJ-EXPERT-RM-01) PNAP-SFJ-EXPERT-RM-01
                                                     63.251.224.0 -
    63.251.224.255
    
    Admittedly I have not investigated any more then a mild look to determine
    if all their server<s> are contained within this netblock.  But, this is
    not unmanageable.  And certainly should be covered in the security policy
    and the corporate AUP.
    
    Thanks,
