AS13113 ISILINE-AS Via Marconi, 2
Residential RIPE Cable/DSL/ISP
Summary
ISI Line
isp hosting business
Three reverse-name formats across two domains, one of which concatenates octets with no separator.
What it's used for
- An Italian internet provider. 35,840 addresses across ten IPv4 prefixes, two IPv6 prefixes, and 56 observed BGP neighbours.
Notable
- Sixteen of 18 sampled addresses returned names in three forms:
host-0-104-253-87.isiline.orgwith the octets reversed,network-213-144-72-0.isiline.netwith them forwards, andhost-79255.isiline.netwith two octets run together. - Two domains are in use, differing only in their top level.
- Netnames are
IT-ISILINEdated from20000228to20160331, plus one built from an individual's name. - The AS handle is
ISILINE-AS Via Marconi, 2, a street address.
Interesting
host-79255is the interesting failure. Two octets joined without a separator cannot be split back apart reliably: the digits could divide in more than one place, and only knowing the block resolves it. The other two formats in the same record keep their separators and do not have the problem.- One reversed format and one forward format, under two top-level domains, from one operator. Each was somebody's generator at some point, and the older zones were never migrated.
- A netname carrying a person's name marks space assigned to an individual customer, kept in the public record exactly as it was typed.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
