Anyone using Earthlink! |
|
|
I will be trying to sort out a simple problem with a colleague who
uses Earthlink.
She has three time asked them for her IP address She has been given an
address 172 xxx xxx xxx. Does not work. Pinged no response.
I have asked her to check with WHAT IS MY IP, as I did for my own and
she came up with two addresses that did not work. Beginning 66.XXX XXX
XXX. My guess one could her machine and the other the ISP's address
for her.
I did a reverse check on the two numbers and they went back to
Earthlink. The other went back I recal to some address in California
OrgName: Internet Assigned Numbers Authority
OrgID: IANA
Address: 4676 Admiralty Way, Suite 330
City: Marina del Rey
StateProv: CA
PostalCode: 90292-6695
Country: US
The other two addresses went back to Earthlink.
OrgName: EarthLink Network, Inc.
OrgID: ERAD
Address: 1375 PECHTREE ST, LEVEL A
City: ATLANTA
StateProv: GA
PostalCode: 30309
Country: US
I reckon some support guy may have got it wrong with the 172 number,
gave had information to my colleague.
Anyone any kind commens that may harbour a suggestion that will be
helpful.

If she is using Earthlink's dial-up, then the IP is going to change each
time she dials and gets a connection.
If this is a Windows O/S machine, she can go to the Command Prompt by
entering COMMAND in the run box and press the enter-key, which will take
her to DOS.
She can then enter IPCONFIG /ALL and press the enter-key, which will show
her the IP the machine has that was issued by the ISP and the DNS IP(s) of
the ISP the machine is using. It doesn't matter if it's a dial-up or not
enter IPCONFIG /ALL at the Command Prompt.

I had a PC problem a short while ago, had to re-install (not a virus).
Before that I did connect so it is possible. For some reason the same
connections are not getting a response.
It is a relative, I have been asked to look in on her system everynow
and then just in case thyere is a simple problem I can help with. More
complicated then a local expert!
Pinging..... when I have had a problem here the first thinmg they do
is ask you to ping certainaddresses. I guess to make sure the basics
are right. I do not have the knowledge to argue.

Of course I ahve asked her to trace her IP address. That is the
information I have used. She got it from Earthlink.

What's preventing her from asking her own computer what address it is using?
If you are using windows NT, w2k, or XP, the command "ipconfig /all".
If you are using Windows 9X, ME then winipcfg and the more button.

In your zeal to hide the IP information, you over did it. But let's see:
[compton ~]$ grep ' 172\.' IP.ADDR/stats/[ALR]*
IP.ADDR/stats/ARIN.gz:US 172.128.0.0 255.192.0.0 allocated
IP.ADDR/stats/ARIN.gz:US 172.192.0.0 1638400 allocated
[compton ~]$ grep -c ' 66\.' IP.ADDR/stats/[ALR]*
IP.ADDR/stats/AFRINIC:2
IP.ADDR/stats/APNIC:0
IP.ADDR/stats/ARIN:754
IP.ADDR/stats/LACNIC:3
IP.ADDR/stats/RIPE:0
[compton ~]$
So, for the 66.XXX.XXX.XXX block, there are 759 ISPs around the world that
have assignments. Pretty useless. On the other hand, ARIN has only two
blocks assigned, which combined are 172.128.0.0 to 172.216.255.255, and
those belong to AOL. I rather doubt that's what you are referring to, but
there is a third address block not listed:

That's 172.16.0.0 through 172.31.255.255. Those addresses are normally
used behind NAT routers. You can't connect to them from the Internet,
because they are not assigned to any one entity, and can be used, like
the more familiar 10.0.0.0 - 10.255.255.255 and 192.168.0.0 - 192.168.255.255
range at homes.
I reckon some support guy may have got it wrong with the 172 number,

No, 172.16.0.0/12 is handed out for systems that do not need to be
contacted directly by someone else on the Internet. Sounds as if your
friend is NATed and not directly reachable from the world, although she
can reach OUT to the world.

Re: Anyone using Earthlink! |

If she has Earthlink DSSL then she is using a PPPoE connection. This
will produce some odd IP configuraions at IPCONFIG. FOr instance,
here's mine.
Connection Type: PPPoE
Internet IP Address: 68.###.###.###
Subnet Mask: 255.255.255.255
Default Gateway: 172.31.255.251
DNS IP Address: 207.###.###.###
MAC Address: 00:13:10:B8:2D:0F
Normally this would be a totally invlaid config since I have no valid
network or valid gateway. But It is not unusual. The 68.###.###.###
is my public address and is pingable BECAUSE I CONFIGURED IT TO BE
PINGABLE.
WIndows XP SP2 blocks all ICMP(ping, traceroute, etc) traffic as part
of the firewall. If you use a Router, they typically offer to ignore
WAN pings. PING is not a completely reliable protocol because many
devices block it to discourage scans and attacks.
If she has a router then her PC would have a local private address
192.168.x.x
172.16.x.x - 172.31.x.x
10.x.x.x
And the router would hold the Internet address.
