Summary

individual consulting linux small

JULE is the autonomous system held by Juliane Holzt.

What it's used for

  • The space carries a single IPv4 prefix, 193.30.42.0/24, with netname JULE-V4 and registrant Juliane Holzt.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix (2a0c:b641:410::/44) while maintaining 27 observed neighbours, a ratio indicative of a small-scale transit or peering arrangement rather than a large access network.

Notable

  • The RDAP registrant Juliane Holzt matches the registry holder and the AS handle JULE, confirming consistent ownership.
  • Secondary sources identify the holder as a self-employed IT consultant and Debian developer based in Bochum, Germany, operating under the professional name "Juli Jane".
  • The address inventory is minimal, consisting of one /24 block and one /46 IPv6 prefix, typical of a personal or small business network.

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: 436 networks and 1,771 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.
