Summary

Zentrale Informatikdienste Kanton Basel-Landschaft

Switzerland · AI-generated

government business internal

The AS handle ZIDBL is held by Zentrale Informatikdienste Kanton Basel-Landschaft.

What it's used for

  • The address space carries internal government IT infrastructure, evidenced by the netname AFI-BL-BLOCK-16 and reverse DNS entries like xfziwebshared04-avs.bl.ch.
  • The AS announces 4096 IPv4 addresses across 4 prefixes and maintains 2 observed neighbours, a ratio indicating an internal corporate or government estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal services for the Canton of Basel-Landschaft government administration.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing Zentrale Informatikdienste ZID Kanton Basel-Landschaft and Zentrale Informatikdienste Kanton Baselland.
  • The address inventory is a contiguous block of four prefixes (193.47.168.0/23, 193.47.170.0/23, 193.47.172.0/22, 193.47.176.0/21) that together form a /21, reflecting a finely subdivided internal estate.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,782 prefixes, as published 2026-10-16. 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.
