AS14524 announces 4 IPv4 prefixes covering 1,792 addresses and 0 IPv6 prefixes.

About this network

Two netnames record a carrier, the word legacy, and the company that carrier absorbed.

What it's used for

• A government services contractor's network. 1,792 addresses across four IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Two blocks are registered to CenturyLink Communications, LLC under the netnames CENTURYLINK-LEGACY-SAVVIS-BLK85 and CENTURYLINK-LEGACY-SAVVIS-BLK186.
• The other two carry SERCO-IN10-72 and NET-209-27-15-0-1.
• The contractor's name is written three different ways across the records, with and without a corporate suffix.
• One of twelve sampled addresses answered, with serconamailgw3.serco-na.com.

Interesting

• A netname carrying both the current carrier and the acquired one, with the word for inherited space between them, is a bulk rename done properly. Somebody renaming thousands of records at once chose to keep the old name visible so that engineers looking for the previous company's space would still find it.
• That is the opposite of the usual outcome, where an acquisition leaves the old name alone and the connection between the two is left for a reader to guess.
• The published hostname marks a mail gateway and numbers it third, so at least three of them handle mail for a contractor whose correspondence is largely with government agencies.
• Two upstreams and one named host is a small, careful public footprint for an organisation whose work is mostly conducted on somebody else's networks.
