Original carrier is not current carrier
Portability changes how an allocation record should be labeled.
The durable clue
A prefix can retain its original range allocation after a customer changes provider.
The missing feed
Static metadata may not include live routing or portability information.
The honest label
Show original carrier with source and date; show current provider only when a separate current source supports it.
Name the field honestly
These are hypothetical interface labels, not actual lookup results.
| Weak interface copy | Better interpretation |
|---|---|
| Carrier: Provider A | Original allocation: Provider A; current provider unknown |
| Verified current network | Only use this if a real current-data check supports it |
| Updated today | Distinguish page publication from dataset/version time |
A well-labelled result discloses what was checked. It does not turn the timestamp of a webpage into the freshness of routing data.
