About this network

The AS handle DISTR-21 is held by District Photo, Inc., a digital imaging and photo fulfillment company based in Beltsville, Maryland.

What it's used for

• The address space carries corporate infrastructure, evidenced by the netname Q1017-65-122-25-0 for the prefix 65.122.25.0/24 and reverse DNS entries pointing to dia.static.centurylink.net.
• With 512 IPv4 addresses announced across 2 prefixes and only 2 observed neighbours, the inventory suggests a small, self-contained corporate network rather than a transit or large-scale access provider.

Notable

• Registrants differ from the announcer for one prefix: 50.227.81.0/24 is registered to Comcast Cable Communications, LLC (netname CCCH3-4), while 65.122.25.0/24 is registered to DISTRICT PHOTO INC.
• The address inventory is small and split between two distinct /24 blocks, one of which appears to be leased or historically associated with a cable provider, while the other is directly owned by the company.
