Summary
Retelit Digital Services
telecom hosting business
Three company names visible at once, 122 neighbours, and addresses written backwards in DNS.
What it's used for
- An Italian business connectivity and data-centre operator. 36,864 addresses across twelve IPv4 prefixes, one IPv6 prefix, and 122 observed BGP neighbours.
Notable
- The largest blocks are
212.29.128.0/19,212.91.64.0/19,80.247.64.0/20,87.248.48.0/20and178.239.176.0/20. - Every netname uses one prefix:
IT-IRIDEOS-980527,20011112,20050810,20070115,20100903and20120227. - The AS handle is
ASN-ENTER; the registered holder is Retelit Digital Services S.p.A. - Eight of eighteen sampled addresses returned names, of the form
host-255-143.29-212.enter.it.
Interesting
- Three different company names appear in one record. The AS handle says one thing, the netnames say another, the holder says a third, and the reverse zone uses the domain of the first. Each layer was written during a different ownership, and none of them is wrong.
- The reverse names reverse the address and split it across two labels:
212.29.143.255becomeshost-255-143.29-212. Working backwards matches how reverse DNS itself is structured, so the script that generates these is following the grain of the system rather than human reading order. 980527is a two-digit year from May 1998, sitting in the same holder's list as six four-digit dates. Elsewhere in this range a two-digit and a four-digit netname share the identical day in October 1999, and one holder used four digits consistently from 1989 onward. The two formats ran side by side for over a decade; the choice was the filer's habit, not a rule that changed.- 122 neighbours on 36,864 addresses is an interconnection business. The addresses serve customers; the peering is the product.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
