About this network

HAMDEN-ASN is operated by Hampden-Sydney College.

What it's used for

• The address space carries campus network traffic, with reverse DNS records indicating administrative (zzz-adm-dhcp), student (zzz-stu-dhcp), and DMZ (zzz-dmz-host) segments under the hsc.edu domain.
• The AS announces 6,656 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit provider.

Notable

• All three announced prefixes share the netname HSC-MAIN-CIDR-01 and list Hampden-Sydney College as the registrant, confirming the space is directly owned and managed by the institution.
• The inventory consists of three contiguous IPv4 blocks within the 72.10.224.0/20 range, with no IPv6 prefixes announced.
• The reverse DNS sample shows a structured naming convention for DHCP pools and DMZ hosts, reflecting a segmented internal network design typical of a college campus.
