isp residential turkey small

BIZIMINTERNET is operated by Bizim Internet ve Bilisim Teknolojileri San. ve Tic. Ltd. Sti., a regional internet service provider based in Kocaeli, Turkey.

What it's used for

  • The address space carries residential and small business internet access, evidenced by the registrant name and the netname TR-BIZIMINTERNET-20180314 for the primary block.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for end-users in the Kocaeli region of Turkey.

Notable

  • The registrants for the two announced prefixes differ: 185.249.88.0/22 is registered to the operator itself, while 31.145.39.0/24 is registered to Borusan Telekom Backbone Group under the netname VFNETTEST-NET, indicating leased or historically allocated space.
  • The inventory consists of one larger /22 block and one smaller /24 block, with no IPv6 prefixes announced.

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
