Summary

BeST (life:)

Belarus · AI-generated

mobile residential isp belarus

The AS handle BEST-AS is held by "BeST" CJSC.

What it's used for

  • The address space carries mobile and fixed-line subscriber traffic, evidenced by registrant netnames such as Life and BY-BEST-20100504 associated with the "life:" brand.
  • The network announces 60,928 IPv4 addresses across 18 prefixes and 4 IPv6 prefixes, with only 1 observed neighbour, indicating a large access network rather than a transit provider.
  • Traffic from this AS consists primarily of subscriber eyeballs for mobile and broadband services in Belarus, as BeST operates the "life:" mobile and fixed-line network.

Notable

  • Registrants consistently list "BeST" CJSC alongside administrative contacts LIFE_BY-ADMIN and LIFE_BY-TECH, aligning with the announcer.
  • Turkcell assumed 100% ownership of "BeST" CJSC, the operator of the "life:" brand in Belarus.
  • The inventory includes a mix of large blocks like 178.154.0.0/17 and numerous smaller /23 and /24 prefixes, reflecting a segmented subscriber address space.

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 1,773 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.
