Summary
A1 Bulgaria
isp telecom mobile
Netnames that map the fibre rollout street by street, and one that still says GPRS.
What it's used for
- Fixed and mobile access in Bulgaria. 40,704 addresses in 42 IPv4 prefixes, two IPv6 prefixes, and one observed BGP neighbour.
Notable
- Two blocks are named for the fibre plant that serves them:
GPON-VelikoTarnovo-South-1andGPON-SofiaSouth-2. 78.90.188.0/22isKRASNO-SELO-SOF, a district of Sofia, registered through Megalan Network hostmaster.85.118.80.0/22isMobiltel_GPRS_Network.- The older allocations carry the previous brand:
BG-MTELNET-20050404,20120123,20120821. - Two sampled addresses answered under
mtel.net.
Interesting
- GPON is the passive optical technology used to run fibre to homes, and naming the blocks after the districts they serve turns the registry into a deployment map. Anyone reading the records learns which neighbourhoods were cut over and in what order, which the operator publishes nowhere else.
GPRSis packet data over 2G, a technology from the late nineties. A live block still carrying that netname means the addresses were assigned for mobile data when that was the only kind, and were never renamed as the network went through 3G, 4G and 5G underneath them.- One observed neighbour against 42 prefixes marks this as a member of a larger group rather than an independent operator. The mobile arm announces its own space and reaches the world through a sibling network, which is an accounting boundary made visible in BGP.

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 1,783 prefixes, as published 2026-10-17. 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.
