Summary
SLB (Schlumberger)
enterprise legacy
A corporate network registered to Schlumberger (SCHLUMBERGER-AS), the oilfield
services company now branded SLB.
What it's used for
- Global corporate and technical networking for the company's operations.
Notable
- An enterprise network, not a commercial ISP or host. The low AS number reflects an allocation from the internet's earliest years.
Interesting
- The AS holds a very large block of IPv4 addresses, a legacy of early, generous allocations to large corporations.
