FiveThirtyEight article Five ThirtyEight article Sixteen Words article Seven Wonders article Seven Stars article Seven Days article Seven Words article Slingbox article Sliced from top to bottom, the list of sites that have used the same IP address for multiple months is a long one.
One site is hosted by a firm known as NetApp, which has been accused of using it for multiple years, according to security researcher Marc-Andreas Schmitz.
The IP address, which NetApp provided to Ars, is a part of the DNS system that allows the company to resolve the domain names of web servers.
NetApp is owned by Microsoft.
“It’s the same exact domain,” Schmit, a security researcher, told Ars.
“The only difference is that NetApp has changed the DNS server to point to a different domain name.”
It’s a tactic known as a reverse DNS, and it’s been around for years.
NetFlix, the video-streaming service that’s owned by Google, has also used a reverse IP address since 2005.
“This is really troubling,” said Brian Krebs, the author of a series of blog posts that detail how companies can hide their IP addresses and other details about their websites.
“There are so many sites out there that use the same server IP address.
And if you are the owner of one of those sites, there’s no way to find out where you are.
There are so few ways for anyone to find you.”
A quick look at NetFlish’s IP address reveals that it’s actually hosted by the same company that hosts many of the popular sites mentioned above.
(NetFlix also hosts other domains like netflix.com, tesla.com and thedailymotion.com.)
“NetFlish has been using the same DNS servers for several years,” said Jason Hesse, a NetFlice employee who told Ars that the company used the domain name as a placeholder when it was trying to host the site.
“Netflix is not hosting this site,” he said.
“We have no way of knowing who is hosting it or where they are.”
Hesse also said NetFlitch doesn’t know why it’s using the IP address and hasn’t seen the company’s IP logs.
“I have no idea what the purpose is, what purpose the company is using it,” he told Ars, “but I have no clue how to stop them.”
Hessler also said the company doesn’t seem to be using the address to host any ads or other content, which is odd considering the fact that the site has over 200,000 monthly visitors.
“They are using the domain in an ad campaign for some unknown reason,” Hesse said.
Netflix isn’t the only company to have used a different IP address to serve their site.
In February, the domain for The Daily Beast, a popular political news site, changed hands for a fraction of what it was worth.
“TDA [The Daily Beast] has used the address of the ISP in the past to host their site and have hosted a large amount of traffic,” The Daily News said in a statement to Ars.
It’s unclear why TDA changed the IP, or why it might be using a different DNS server.
It also didn’t respond to Ars’ request for comment.
“A company that has repeatedly used the IP of another site as a server address for their web hosting company for the past decade and a half should be required to stop this practice immediately,” said Hesse.
“While the site may have been hosting ads or content previously, it should not be used to serve adverts or other malicious content to people without a valid reason to do so.”
Ars has contacted NetFlices parent company for comment and will update this article when we hear back.
