About this network
A German provider selling business connectivity and hosting.
What it's used for
- Business access and hosted services. 34,048 addresses across six prefixes, one IPv6 /32, six observed BGP neighbours.
Notable
- Four of the six prefixes are /19s, each with its own dated netname: DE-LFNET-990409, DE-LFNET-19990722, DE-LFNET-20010716 and DE-LFNET-20050308, with DE-LFNET-20170815 on a later /22.
- The first two are three months apart and written differently. One uses a two-digit year and the other four, in the same registry, for the same holder, in the same year.
- The sixth block, 192.188.136.0/24, carries an unrelated netname, XOF-NET.
Interesting
- Those two 1999 netnames settle something. RIPE's date-stamped netnames are useful for dating parts of a network, and it is tempting to read the two-digit and four-digit forms as an era each — before and after some cutover. This holder used both inside four months, which means the form follows whoever filed the request rather than when it was filed. Date the block from the digits, not from the style.
- A /19 is 8,192 addresses, and getting four of them between 1999 and 2005 was a matter of demonstrating need to a registry that was already rationing. The /22 from 2017 is what the same company could get once the free pool was gone: a sixteenth as much, eighteen years later.
