AS9927 PHILCOMNET-PH Philippine Global Communications Corporation

AS9927 (PHILCOMNET-PH) is held by Philippine Global Communications Corporation, trading as PhilCom, a telecommunications carrier and ISP headquartered in Makati City. It is one of the older Philippine carriers to hold its own ASN and operates as a multihomed commercial internet provider.

What it's used for

The routing evidence points at a mid-sized commercial ISP rather than a mass-market eyeball network. RIS sees 67 IPv4 prefixes carrying only 17,152 addresses — an average of roughly a /24 apiece, which is the signature of a network handing out small, individually routed blocks to business customers rather than aggregating large residential pools. The announced space is drawn from three separate APNIC ranges (202.57.x, 58.97.x, 45.64.x, plus 103.21.13.0/24), consistent with allocations picked up over a long period. A single IPv6 prefix, 2405:d400::/32, is announced. The 37 observed neighbours is the interesting number: that is far more peering than an enterprise or a pure access network of this size would ever need, and it lines up with PhilCom's own positioning as a multihomed carrier that both buys transit from several upstreams and resells connectivity onward to Philippine corporate customers and smaller providers.

Notable

• Sits in the second tier of Philippine carriers — smaller in address terms than the PLDT or Globe eyeball networks, but with a peering footprint out of proportion to its size.
• The many-prefixes-few-addresses shape is typical of a leased-line and corporate-connectivity business, where each customer site gets its own routed block.
• The 45.64.x and 103.x space is recent-era APNIC allocation, showing the network has kept growing past its original assignments.
