AS14531 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

One hostname names a security zone, a project, a service and its instance number.

What it's used for

• A defence and aerospace contractor's network. 256 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.

Notable

• One sampled address answers as dmz-proj-semafor-service-10.atl.external.lmco.com, which names a security zone, a project, a role, an instance number and a site in one string.
• The whole footprint is 192.35.37.0/24, carrying the netname GE4 and registered to the company.
• That netname is two letters of a company absorbed into this one long ago, plus a counter.
• The AS handle pairs the company's initials with the same site code as the hostname.

Interesting

• The hostname is a small map. It tells a reader which zone the host sits in, that the zone faces outward, which project owns it, what it does and that there are others like it. Internal naming conventions are useful precisely because they carry that much, and publishing one in the reverse DNS hands the same convenience to anybody who looks.
• Naming a project in a public record is the part worth flagging for an organisation in this sector, and it costs nothing to strip.
• The netname preserves a corporate ancestor two mergers back, which is the usual fate of these fields.
• Two upstreams and a single small block, with the vast majority of a contractor of this size living on networks that are not routed publicly at all.
