Summary

Vayfi

Turkey · AI-generated

business telecom turkey

VAYFI is operated by Vayfi Bilgi Teknolojileri A.S., a Turkish telecommunications provider specializing in corporate internet and connectivity solutions.

What it's used for

  • The address space carries corporate and business connectivity traffic, evidenced by netnames such as TR-VAYFI-20190809 and Vayfi-BT, alongside leased blocks from Netfactor Telekominikasyon and SUMER VARLIK YONETIM A.S.
  • With 3072 IPv4 addresses across 10 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to Vayfi Bilgi Teknolojileri A.S., though some blocks are held by Cogent Communications Hostmaster and Netfactor Telekominikasyon ve Teknoloji Hizmetleri San. ve Tic. A.S.
  • The address inventory is finely subdivided into ten distinct prefixes, ranging from /23 to /24 blocks, reflecting a segmented corporate estate rather than a single contiguous allocation.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
