Summary

TEA Ltd

Bulgaria · AI-generated

hosting isp legacy

AS8431 belongs to TEA Ltd of Sofia, one of Bulgaria's long-standing internet companies. It sells business internet access in Sofia and Plovdiv alongside web hosting, VPS, colocation and IT support. Many datasets show its name as "Sofia, Bulgaria" — that is the registry's location field, not a company name.

What it's used for

  • Corporate connectivity and hosted services. The reverse DNS across 195.230.0.0/19 is a roll-call of customer names: individual hosts and gateways under tea.bg are named after the businesses behind them, with the provider's own routers and address pools mixed in.
  • Just under 5,000 IPv4 addresses in nine prefixes, all from a single legacy allocation, with no IPv6 announced.

Notable

  • Business and hosting space, not eyeball space. There are no dynamic subscriber pools here. An address in this range is most likely a customer's server or a leased-line site.
  • The AS peers with a large number of Bulgarian networks relative to its size, which is what a small local provider looks like when it sits on the national exchange: many peers, few upstreams, little address space.

Interesting

  • The allocation's netname encodes its own date, 960917 — September 1996 — which is a fair marker of when this network first came online, back when a Bulgarian ISP named each customer's gateway by hand.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
