Summary

Gemzo

Palestine, State of · AI-generated

isp residential palestine telecom

The AS handle GEMZO is held by Gemzo information technology Private Joint-Stock company.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as 255net178-214-71.gemzo.net and gemzo255-109-73-251.gemzo.net.
  • The AS announces 15,872 IPv4 addresses across 12 prefixes with only 3 observed neighbours, a ratio indicative of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business connectivity, consistent with Gemzo's role as a telecommunications provider established in 2005.

Notable

  • Registrants are split between Gemzo information technology Private Joint-Stock company (netname GEMZO) and GlobalCom Telecommunications PLC (netname PS-GLOBALCOM-20091016), with the latter holding several prefixes including 109.73.248.0/21 and 109.73.240.0/22.
  • The address inventory is divided between two distinct netnames, suggesting a consolidation of previously separate allocations or a partnership arrangement between the two entities.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
