About this network

QSP is a Dutch provider running connectivity and hosted services from its own space.

What it's used for

• Connectivity and hosted services. One sampled address answers as out01.townmail.nl, an outbound mail relay.

Notable

• 10,240 addresses across four prefixes, five observed BGP neighbours.
• Three blocks are QSP's own — NL-QSP-19990917 from September 1999, NL-QSP-20170727 from July 2017, and one simply named QSPNET. The fourth, 185.55.20.0/23, is registered as NL-PCGIT-20140424 to PCG-IT B.V.
• The IPv6 allocation is a 2a04:c580::/29, which is eight times the size of the /32 most providers of this scale receive.

Interesting

• The two dated netnames are eighteen years apart and show the same registry in two moods. NL-QSP-19990917 was written when the company was new and IPv4 was still being handed out on request. NL-QSP-20170727 was written after exhaustion, when a /22 was the largest allocation available to anyone at all — and sure enough, that is exactly what it is.
