Summary
MobiFone
isp mobile eyeball
MobiFone is one of Vietnam's major mobile operators, a state-owned carrier.
What it's used for
- Mobile voice and data for a large Vietnamese subscriber base, plus mobile-broadband services.
Notable
- A large "eyeball" network: addresses here are typically consumer mobile devices, often behind carrier-grade NAT.
- Competes with Viettel and VNPT's VinaPhone as one of Vietnam's big three mobile operators.
Interesting
- MobiFone was Vietnam's first mobile network and was later separated from the VNPT group to operate as an independent state enterprise.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
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 1,768 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.
