Summary
SURF (SURFnet)
education research legacy
The Netherlands' national research and education network (SURFNET-NL), operated
by SURF and based in Utrecht.
What it's used for
- High-capacity backbone connecting Dutch universities, colleges, research institutes, and academic hospitals to each other and to the global research internet.
Notable
- A national research and education network (NREN), not a commercial ISP. It announces a large amount of IPv4 space on behalf of the Dutch academic community.
Interesting
- SURFnet is one of the pioneering European NRENs, which is reflected in its low AS number.
