About this network

The AS handle SERVERCENTRAL is held by ServerCentral, a US-based web hosting and email services provider.

What it's used for

• The address space carries hosting and email infrastructure, evidenced by netnames like SCN-3, SCN-6, and SL-2063, and reverse DNS entries pointing to servercentral.net and smtp2go.com.
• With 134,144 IPv4 addresses and 104 IPv6 prefixes announced against 49 observed neighbours, the ratio suggests a hosting or business network rather than a transit provider.

Notable

• Registrants for the majority of prefixes are listed as DEFT.COM, while one block (158.120.80.0/21) is registered to Sand Dune Mail Ltd under the netname SMTP2GO-NZ.
• The address inventory is finely subdivided into 258 IPv4 prefixes, indicating a structured internal estate or leased space arrangement.
