About this network

SYNN is the AS handle for Synergy Networks.

What it's used for

• The address space carries legacy business and enterprise allocations, evidenced by netnames such as WLCO-TWC481067-SYNERG and CENTURYLINK-LEGACY-EMBARQ-BKL-4.
• The AS announces 9984 IPv4 addresses across 12 prefixes with only 2 observed neighbours, a ratio that indicates a small, isolated business or legacy network rather than a transit provider.

Notable

• Registrants are predominantly Synergy Networks, though one prefix (67.238.54.0/24) is registered to CenturyLink Communications, LLC, reflecting historical acquisition or lease of the space.
• The inventory consists of a mix of /21, /22, /23, and /24 blocks, including legacy CenturyLink and Embarq space, suggesting a fragmented estate inherited from prior telecom operators.
