What it's used for

• The address space carries residential broadband and voice services, evidenced by reverse DNS names such as syn-098-008-200-000.inf.spectrum.com and syn-016-014-242-000.voip.spectrum.com.
• With 40448 IPv4 addresses announced against only 7 observed neighbours, the ratio indicates a large access or eyeball network rather than a transit provider.

Notable
