[arin-tech-discuss] API breakage after website change

[Brian Rak]

We noticed that something broke with the API with the new website.  We 
used to hit URLs like this:

https://reg.arin.net//rest/report/reassignment/NET6-2001-19F0-1?apikey=xxxx

However, these have started throwing 404s now.  In addition, they 
redirect us to the non-existant domain http.arin.net:

$ wget --spider 
https://reg.arin.net//rest/report/reassignment/NET6-2001-19F0-1?apikey=xxxx
Spider mode enabled. Check if remote file exists.

Resolving http.arin.net (http.arin.net)... failed: Name or service not 
known.
wget: unable to resolve host address ‘http.arin.net’

In this case, it's the duplicate slash in the URL that's causing the 
problem, so the workaround on our end is pretty straightforward, but I 
was not expecting this to break with the website change.
