Summary
Merck & Co.
enterprise legacy
MERCK is the corporate network of Merck & Co., Inc., the American pharmaceutical company (known as MSD outside the United States and Canada). ARIN registered the ASN in 1996.
What it's used for
- Enterprise networking for Merck: corporate sites, research and manufacturing facilities, and internet-facing company services.
- The AS announces its address space out of the
155.91.0.0/16legacy block, carved into dozens of smaller prefixes that map to individual company locations.
Notable
- Reverse DNS resolves under
merck.com, and there is no subscriber or hosting-style naming anywhere in the space. This is a pure corporate network that sells no connectivity. - Merck is one of several large pharmaceutical companies that took their own AS number and Class B block in the 1990s. Compare [AS7068](https://asn.ipinfo.app/AS7068), Pfizer's, registered days apart.
