About this network

Three sampled addresses, three different services, all numbered.

What it's used for

• An internet service provider's network. 256 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.

Notable

• The sampled addresses answer as mail4.islc.net, web3.islc.net and ts7a127.islc.net.
• The whole footprint is 216.49.160.0/24, carrying the netname ISLC and registered to the company.
• The AS handle is the same four letters again.
• Three addresses were queried for reverse DNS and all three returned a name.

Interesting

• Sampling three addresses at random and hitting three distinct roles means the block is densely used, which is unusual in this range where most sampled addresses answer with a carrier template or nothing at all. The counters say there are at least four mail hosts and three web hosts behind these names.
• The third name embeds the last part of its own address, a convention from terminal and access server pools where each line needed a predictable name.
• Naming services plainly is the old provider convention and it works: a reader learns the shape of the network from three lookups. It also tells anybody scanning exactly which host to try first.
• Handle, netname and registrant all agree, so nothing here has been renamed or resold.
