I notice a weird issue like this with Alibaba when i try to use my Comcast 
connection. Turn my wifi off and now it works flawlessly.

Are you using your comcast connection?

Not very long ago I worked for a well-known e-commerce platform where we nearly
ran out of RFC1918 space. We seriously considered using what was then
un-advertised DOD space to supplement RFC1918 space inside our data centers.

Perhaps AliExpress did get to that level of desperateness?

Thanks,

No idea. The IP address does not reply to HTTP requests, anyway. A
practical joke?

Note that this redirection takes places only when there is no
User-Agent field. If you say 'User-Agent: Mozilla', you get a proper
redirection, in my case to https://fr.aliexpress.com/.


Interesting Ali Express web server behavior...

2023-12-09 Thread Owen DeLong via NANOG
So I’m having trouble connecting to the Ali Express web server this evening and 
decided to investigate a little.

What I found surprised me…

… OK, so far so good, though the hard coded IP redirect is a bit odd. 
Especially when you consider this:

Which seems in line with the announcement of that address I’m seeing:

(AS749 is also DISA/DDI)

But why would AliExpress be redirecting to DDN space? Is this legitimate? Ali 
hoping to get away with squatting, or something else?
