Summary
GTS Central Europe (T-Mobile Czech Republic)
transit isp legacy
GTSCE was the backbone AS of GTS Central Europe, an alternative business-focused carrier operating across the Czech Republic, Poland, Hungary, Romania and Slovakia. Deutsche Telekom acquired the GTS group in 2014, and the registration now sits with T-Mobile Czech Republic a.s.
What it's used for
Regional transit and enterprise connectivity: leased lines, IP transit, MPLS/VPN and data-centre services sold to business customers rather than households. The AS retains its own peering presence — the RIPE object still advertises a 20 Gbit/s DE-CIX port and a peering@gtsce.net contact.
Notable
This is a carrier/enterprise-services network, not T-Mobile's mobile or consumer broadband AS. Despite the holder name, addresses here should not be read as mobile subscribers. The former "Antel Germany" reference in the description is a remnant of the group's German footprint.
Interesting
GTS's Romanian arm keeps a separate registration and AS number — see AS5606 — so the two GTS networks appear as distinct autonomous systems even though they share a corporate history.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
