Residential RIPE Cable/DSL/ISP
Summary
1&1
isp residential eyeball dsl fiber
1&1 (ONEANDONE) — a major German consumer telecom and residential-broadband brand, part of the United Internet / 1&1 group.
What it's used for
- Residential DSL and fibre home internet (and mobile) for German households, largely resold/wholesaled over Deutsche Telekom and other access networks.
Notable
- A large "eyeball" network: addresses here are German home connections, not servers. 1&1 is one of Germany's biggest consumer ISPs behind Deutsche Telekom and Vodafone.
Interesting
- 1&1 has been building out its own mobile network, but its fixed home-broadband base is delivered largely over wholesale access to incumbent lines.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
