In reply to a post by Hatari:

There are groups of IPs that are reserved for private use frequently as equipment IPs and private LAN IPs.

i.e. 192.168.0.0 - 255.255, 10.0.0.0 - 255.255.255 & 172.16.0.0 - 31.255.255 see RFC 1918 & RFC 3330.

Hope that helps

Do you think there's a problem with them appearing in a traceroute?

I would not have expected reserved IPs to appear in a tracert on the public web. As I type I am not sure what router the OP has and what its IP address range is. The only time I would expect reserved IPs to appear is where there is another router between the computer/router and the public net. I think the possible problem here is a wifi one and testing with a wired connection would confirm one way or another.

The connection has to go through the ISP network to reach the "public web"

So does yours and mine, the IPs used are not reserved Anyone of them can be resolved using whois. The ISP's network is classified as public in the terms we are talking in. See the tracert from here. Don't worry about the latency the ISP has a backhaul problem that should be sorted by mid Jan. I hope.

Trace complete.

In most cases they aren't RFC1918 addresses but in some they are - try this on a 3G network and you'll nearly always get 10.x.y.z addresses.

I ask again - what relevance does this have to the OP?

The 3G network is a mobile phone wireless network and is private.

If the router has a problem then it is possible for the internal router IPs to show. As I posted a lot earlier I believe this is a wifi problem, test cabled and see.

So you're saying a 3G ISP network is private but a fixed line ISP network isn't? Why?

I thought you were a "Very rich and succesful Comms Professional!" so I will assume you know the IANA rules.

As I do not see how this is helping the OP and on my Forum would be classified as ....

I have suggested that the OP needs to do a wired test.

My apologies ss_4

So you can't answer the question then?

The use of RFC1918 addresses in the ISP network, whether it's fixed or wireless, is perfectly acceptable - within the IANA rules and anyone else's.

I agree that this is not helping the OP, I have pointed this out several times but you have pursued the 'private address' scenario which has nothing to do with the OP's problem.

*edit* - spelling
