AS13726 — APS-AS

AS13726 announces 2 IPv4 prefixes covering 4,352 addresses and 0 IPv6 prefixes.

About this network

Reverse names split the address in half: two octets hyphenated backwards, the other two as dotted labels.

What it's used for

• A city school district's network. 4,352 addresses across two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• 173.242.68.0 answers as static-0-68.242.173.atlantapublicschools.us.
• The last two octets are hyphenated in reverse order, and the first two are separate dotted labels, also reversed.
• The district's own /20 is netname ATLANTA-PUBLIC-SCHOOLS, with a network manager as contact.
• 168.9.22.0/24 is netname GDOENET and is registered to the state education department instead.
• The domain ends in a country-level suffix rather than the usual educational one.

Interesting

• Splitting an address across two different separators in one hostname is a zone built by pointing the delegation at a subdomain per range, then generating names inside it. The result reads as two conventions colliding in the middle of one string.
• An address ending in zero having a name at all means the zone covers every slot in the range rather than only the usable ones, which is why the first entry sampled is one no machine can hold.
• A district carrying a state department's block under the same AS is public sector address space pooled the way rural providers pool theirs: whoever had the allocation kept it, and one network announces both.
