how to find GoToMyPC's network

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
Hi All,

    I am trying to stop unauthorized traffic to and from GoToMyPC (and
a list
of others).  How to I figure out GoToMyPC's network for my iptables
"-d" entry?   (...0/24 may not always be the case,
on subnet mask.)

    I can get a particuar IP with "" (
that only gives me one address.  I what to block their entire domain,
including (  Somehow I think that
"-d" would be overkill and may actually block some
legitimate traffic.

    Is there some network command that will tell me this?  (Then I can
grep, sed, and awk my heart out!)

Many thanks,

Try whois on the ip address.

When someone says "I want a programming language in which I need only
say what I wish done," give him a lollipop.

Well, a 'whois' on the domain returns

  Expertcity, Inc.
     5385 Hollister Ave
     Suite 111
     Santa Barbara, CA 93111
   Domain Name: GOTOMYPC.COM

and then asking about the address at ARIN, I find

  Internap Network Services PNAP-06-2001 (NET-66-150-0-0-1)
  Expertcity PNAP-SJE-EXPERT-RM-02 (NET-66-151-158-0-1)

and asking about 'NET-66-151-158-0-1' does indeed return the same
postal address information.

I can't say - we're blocking the /15, and none of my users are complaining
about missing anything - YMMV.     Looking at , doesn't appear to be
listed directly, but if you google for specific address ranges in the
newsgroups "*" you'll probably turn up some hints
about who "owns" an address range, and any problems others are reporting.

Most distributions come with a 'whois' tool - there are quite a number of
them.  Try 'locate whois' and see if one is installed on your system.

Some RFCs to look at:

  1834 Whois and Network Information Lookup Service, Whois++. J.
       Gargano, K. Weiss. August 1995. (Format: TXT=14429 bytes) (Status:

  2167 Referral Whois (RWhois) Protocol V1.5. S. Williamson, M. Kosters,
       D. Blacka, J. Singh, K. Zeilstra. June 1997. (Format: TXT=136355
       bytes) (Obsoletes RFC1714) (Status: INFORMATIONAL)

  3912 WHOIS Protocol Specification. L. Daigle. September 2004. (Format:
       TXT=7770 bytes) (Obsoletes RFC0954, RFC0812) (Status: DRAFT STANDARD)

The major problem is knowing who to ask. For IP addresses, you would start
with the five Regional Internet Registry (AFRINIC, APNIC, ARIN, LACNIC, and
RIPE). See to get a clue
as to which to ask.  They _might_ refer you to other registrars, or they
might refer you to a 'rwhois' server.

For domain names, it's a LOT more complicated. ISO-3166 (two letter country
code) domains can often be found using the five RIRs. Dot coms/net/org/edu
(meaning .com, .net, and so on) should start at IANA, which will identify
the whois server of the domain registrar to contact.  .org, .info, .biz, and
the like are much more fun.

[compton ~]$ grep -v '^[A-Z][A-Z] ' domains | column
AERO    BIZ     COM     EDU     INFO    JOBS    MOBI    NAME    ORG     TRAVEL
ARPA    CAT     COOP    GOV     INT     MIL     MUSEUM  NET     PRO
[compton ~]$ provides a miniscule more information on
these domains, and what they are used for.
