About this network

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) and MULLVA-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.
