Unclassified ARIN Educational/Research
Summary
SB Professional Services
vpn business leased
The AS handle SB is held by SB Professional Services.
What it's used for
- The address space carries a mix of corporate and third-party infrastructure, evidenced by the netnames
SB-FMT-IPV4-02(registrant SB Fremont) andMULLVA-85-203-54-0(registrant Mullvad VPN AB). - The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that suggests a small, isolated network rather than a transit provider.
Notable
- Registrants do not fully agree with the announcer; while one prefix is registered to SB Fremont, the other is registered to Mullvad VPN AB, indicating leased or acquired space.
- The address inventory consists of two distinct /24 blocks, one in the 23.144.160.0 range and one in the 85.203.54.0 range, with no IPv6 prefixes in inventory.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
