Summary
TBISS
isp residential eyeball
TBISS (T Bros Internet & Support Services) is a Bulgarian internet service provider, classified as a Cable/DSL/ISP eyeball network, operating in Bulgaria and neighbouring south-east Europe.
What it's used for
- Residential and small-business broadband internet access for consumers in Bulgaria and the surrounding region.
Notable
- An "eyeball" network: addresses here are end-user home connections rather than servers.
- A regional provider that peers openly at exchanges in Sofia and across Greece (Thessaloniki, Athens) rather than a national incumbent.
Interesting
- Interconnection footprint spanning Bulgaria and Greece reflects the cross- border reach common among smaller Balkan ISPs.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
