BGP announcements for an IP address

Few example scenarios:

• Multiple announcements from single ASN:

• Same announcement from multiple ASNs:
  
  • https://api.telcodb.net/v1/bgpann?format=json&q=192.88.99.1 (GUI)
  • https://api.telcodb.net/v1/bgpann?format=json&q=2002:: (GUI)

Please report bugs on the BGP announcement API on our GitLab.
